[0036] In related technologies, air handling units are equipped with refrigerant leak sensors to detect refrigerant leaks. Since these sensors are consumable parts requiring maintenance and replacement, they are detachably connected to other components of the air handling unit. In some existing technologies, the refrigerant leak sensor is directly fixed to the air handling unit's housing, resulting in limited operating space and difficulties in disassembling and repairing the sensor. In other existing technologies, a mounting box is provided on the air handling unit's housing, with the refrigerant leak sensor fixedly connected to it. However, this approach still suffers from difficulties in installing the sensor and mounting box, and the wiring is complex, offering limited improvement in the efficiency of disassembly and repair.

[0037] The following is for reference. Figures 1-3 This invention describes a sensor mounting box 1 for an air handling equipment according to an embodiment of the present invention.

[0038] like Figures 1-3As shown, the sensor mounting box 1 for an air handling equipment according to the present invention is suitable for mounting sensors and includes a housing 10. The housing 10 defines an mounting space 10a suitable for mounting sensors. The housing 10 has a first sidewall 11 and a second sidewall 12 that are opposite to and spaced apart in a first direction. The first sidewall 11 and the second sidewall 12 both extend along a second direction and define a mounting opening 10b communicating with the mounting space 10a at one end on the same side in the second direction. The second direction intersects the first direction. The distance between the first sidewall 11 and the second sidewall 12 gradually increases in the direction toward the mounting opening 10b. Specifically, the sensor mounting box 1 is the carrier structure for the sensor. The housing 10 of the sensor mounting box 1 can be pre-fixed to other structures of the air handling equipment during the production process. If it is necessary to disassemble and repair the sensor, the sensor can be installed into the installation space 10a through the mounting port 10b, or the sensor can be removed from the installation space 10a through the mounting port 10b. Here, by designing the housing 10 such that the distance between the first side wall 11 and the second side wall 12 gradually increases in the direction towards the mounting port 10b, the housing 10 has a mounting port 10b that gradually opens outwards, which can guide the sensor to be installed into the installation space 10a through the mounting port 10b, making it convenient for operators to perform sensor disassembly and repair operations, and improving the efficiency of sensor disassembly and repair.

[0039] According to the present invention, the sensor mounting box 1 for air handling equipment has a housing 10 designed such that the distance between the first side wall 11 and the second side wall 12 gradually increases in the direction toward the mounting port 10b, so as to guide the sensor to be installed into the mounting space 10a through the mounting port 10b. The design of the first side wall 11 and the second side wall 12 can simplify the sensor disassembly and assembly operation, and the sensor mounting box 1 and the sensor are simple and convenient to disassemble and assemble, which is convenient for operators and can improve the efficiency of sensor disassembly, assembly and maintenance.

[0040] In some embodiments, the sensor may refer to a refrigerant leak sensor, which is suitable for detecting refrigerant leaks in air handling equipment. Since the refrigerant leak sensor is a consumable component, it requires maintenance and replacement during use. The sensor mounting box 1 designed according to this invention enables convenient replacement of the refrigerant leak sensor, allowing operators to disassemble and repair it without tools by simply pulling it out. The sensor can be directly inserted or removed through the mounting port 10b for repair, replacement, or addition, making the operation simple and convenient, and increasing the efficiency of sensor disassembly and maintenance.

[0041] Of course, the housing 10 not only has the first sidewall 11 and the second sidewall 12, but also other sidewalls that connect the first sidewall 11 and the second sidewall 12. For example, as Figure 3As shown, the housing 10 also has a third sidewall 13 and a fourth sidewall 14, which face each other in a third direction. The third direction intersects the first direction and the second direction, respectively. The third sidewall 13 is connected to the first sidewall 11 and the second sidewall 12 on the same side in the third direction, and the fourth sidewall 14 is connected to the first sidewall 11 and the second sidewall 12 on the other side in the third direction. The housing 10 also has a fifth sidewall 15, which is connected to the first sidewall 11, the second sidewall 12, the third sidewall 13, and the fourth sidewall 14 on the side in the second direction away from the mounting opening 10b. In this case, the first sidewall 11, the second sidewall 12, the third sidewall 13, the fourth sidewall 14, and the fifth sidewall 15 together define a mounting space 10a suitable for mounting the sensor.

[0042] Furthermore, the fact that both the first sidewall 11 and the second sidewall 12 extend along the second direction can mean that the extension direction of the first sidewall 11 is parallel to or forms a certain angle with the second direction. The extension of the first sidewall 11 along the second direction means that the first sidewall 11 has a larger size in the second direction. Similarly, the extension direction of the second sidewall 12 can also be parallel to or form a certain angle with the second direction. The extension of the second sidewall 12 along the second direction means that the second sidewall 12 has a larger size in the second direction.

[0043] Furthermore, the first sidewall 11 and the second sidewall 12 can be arranged in a general way that is inclined relative to each other, in which case the extension direction of the first sidewall 11 intersects the extension direction of the second sidewall 12. Alternatively, a portion of the structure of the first sidewall 11 and a portion of the structure of the second sidewall 12 can be arranged in a way that is inclined relative to each other, in which case the extension direction of a portion of the first sidewall 11 intersects the extension direction of a portion of the second sidewall 12.

[0044] According to some embodiments of this utility model, such as Figures 1-3As shown, the first sidewall 11 includes a first segment 111 and a second segment 112 connected to each other, and the second sidewall 12 includes a third segment 121 and a fourth segment 122 connected to each other; wherein the first segment 111 and the third segment 121 are directly opposite each other in a first direction; the second segment 112 and the fourth segment 122 are opposite each other in a first direction, and the end of the second segment 112 away from the first segment 111 and the end of the fourth segment 122 away from the third segment 121 define a mounting opening 10b, and the distance between the second segment 112 and the fourth segment 122 gradually increases in the direction away from the first segment 111 and the second segment 112. Specifically, the extension directions of the second segment 112 of the first sidewall 11 and the fourth segment 122 of the second sidewall 12 intersect. The second segment 112 of the first sidewall 11 and the fourth segment 122 of the second sidewall 12 are inclined relative to each other, and the end of the second segment 112 away from the first segment 111 and the end of the fourth segment 122 away from the third segment 121 extend in a direction away from each other, so that the distance between the second segment 112 and the fourth segment 122 gradually increases in the direction away from the first segment 111 and the second segment 112, thereby defining a mounting opening 10b that gradually opens outward, so as to guide the sensor to be installed into the mounting space 10a through the mounting opening 10b.

[0045] According to some embodiments of this utility model, such as Figures 1-3 As shown, the housing 10 also has a third sidewall 13 and a fourth sidewall 14, which face each other in a third direction. The third direction intersects the first direction and the second direction, respectively. The third sidewall 13 is connected to the first sidewall 11 and the second sidewall 12 on the same side in the third direction, and the fourth sidewall 14 is connected to the first sidewall 11 and the second sidewall 12 on the other side in the third direction. The end face of the third sidewall 13 facing the mounting port 10b is a first inclined surface 131, which extends along the third direction and is inclined in the second direction away from the fourth sidewall 14. And / or, the end face of the fourth sidewall 14 facing the mounting port 10b is a second inclined surface, which extends along the third direction and is inclined in the second direction away from the third sidewall 13.

[0046] Specifically, the third sidewall 13 is adapted to abut against one side surface of the sensor in the third direction, and the fourth sidewall 14 is adapted to abut against the other side surface of the sensor in the third direction. In order to avoid the third sidewall 13 and the fourth sidewall 14 from hindering the movement of the sensor during the disassembly and maintenance of the sensor, at least one of the third sidewall 13 and the fourth sidewall 14 can be designed as an inclined structure with the end face facing the mounting port 10b inclined, so as to guide the sensor toward the mounting space 10a while avoiding hindering the disassembly and maintenance of the sensor, and further improve the efficiency of the disassembly and maintenance of the sensor.

[0047] In some embodiments, the third sidewall 13 is connected to the first segment 111 of the first sidewall 11 and the third segment 121 of the second sidewall 12 on the same side in the third direction, and the fourth sidewall 14 is also connected to the first segment 111 of the first sidewall 11 and the third segment 121 of the second sidewall 12 on the other side in the third direction. In this case, the second segment 112 of the first sidewall 11 and the fourth segment 122 of the second sidewall 12 protrude from the third sidewall 13 and the fourth sidewall 14 in a second direction, and the end of the second segment 112 away from the first segment 111 and the end of the fourth segment 122 away from the third segment 121 face away from each other. The second segment 112 and the fourth segment 122 are extended in a direction away from the first segment 111 and the second segment 112, thereby defining a gradually opening mounting opening 10b. The second segment 112 and the fourth segment 122 can guide the sensor to move toward the mounting space 10a. Furthermore, the end faces of the third sidewall 13 and / or the fourth sidewall 14 facing the mounting opening 10b extend along the third direction and are inclined in the second direction, so as to guide the sensor to move toward the mounting space 10a while avoiding obstructing the sensor's disassembly and assembly, thereby improving the efficiency of sensor disassembly, assembly and maintenance.

[0048] It is worth mentioning that the sensor mounting box 1 is usually designed in a relatively small space in the air handling equipment, where the operator's field of vision is poor. In order to facilitate the operator to disassemble and repair the sensor in the confined space, the sensor mounting box 1 designed according to this utility model is designed such that the distance between the second segment 112 and the fourth segment 122 gradually increases in the direction away from the first segment 111 and the second segment 112, so that the second segment 112 and the fourth segment 122 play a guiding role for the sensor. Furthermore, by designing a first inclined surface 131 on the third side wall 13 of the housing 10 and / or a second inclined surface on the fourth side wall 14, the third side wall 13 and / or the fourth side wall 14 play a guiding role for the sensor. The multiple guiding designs of the housing 10 can increase the success rate of installing the sensor into the installation space 10a through the mounting port 10b, reduce the difficulty of operation in the confined space, and thus improve the efficiency of sensor disassembly and repair.

[0049] According to some embodiments of this utility model, such as Figure 3As shown, the third sidewall 13 includes two ribs 130 spaced apart in a first direction. One rib 130 is connected to the first sidewall 11, and the other rib 130 is connected to the second sidewall 12. The ribs 130 extend in a second direction, and their ends adjacent to the mounting opening 10b in the second direction are spaced apart from the mounting opening 10b and have a first inclined surface 131. Specifically, the ends of the ribs 130 adjacent to the mounting opening 10b in the second direction are spaced apart from the mounting opening 10b. At this time, the second segment 112 of the first sidewall 11 and the fourth segment 122 of the second sidewall 12 protrude from the third sidewall 13 and the fourth sidewall 14 in the second direction to define the mounting opening 10b, which gradually opens outward. Furthermore, the design of the first inclined surface 131 can guide the sensor toward the mounting space 10a while avoiding obstructing the sensor's disassembly and assembly, thereby improving the efficiency of sensor disassembly and maintenance.

[0050] Here, the housing 10 can be as follows: Figure 1 The structure shown resembles a box. In this case, the third sidewall 13 is located on the same side of the first sidewall 11 and the second sidewall 12 in the third direction and is composed of two protruding ribs 130. One protruding rib 130 is connected to the first sidewall 11, and the other protruding rib 130 is connected to the second sidewall 12. The protruding rib 130 can abut against the surface of the sensor in the third direction, thereby limiting the sensor and preventing the sensor from coming out of the installation space 10a from the third sidewall 13. This design of the third sidewall 13 can reduce the material used for the third sidewall 13, reduce the cost of the sensor mounting box 1, reduce the thickness of the sensor mounting box 1 in the third direction, and allow the third sidewall 13 to avoid the sensor surface structure, which facilitates the installation of the sensor.

[0051] In other embodiments, the housing 10 may also be a box-shaped structure with an opening on one side. In this case, the third sidewall 13 may extend as a whole in the first direction and be connected to the first sidewall 11 and the second sidewall 12 on the same side in the third direction. The housing 10 serves to support and install the sensor, and the sensor is installed into the installation space 10a through the installation port 10b.

[0052] According to some embodiments of this utility model, such as Figure 1 As shown, a detection port 14a is provided on the fourth side wall 14 to connect the installation space 10a with the outside, so that the detection part of the sensor is exposed, facilitating the sensor to detect the corresponding data. The detection port 14a can be regular or irregular in shape, and its specific shape is not limited. Here, the sensor can refer to a refrigerant leak sensor, temperature sensor, pressure sensor, etc., which can be selected according to the actual situation.

[0053] In some embodiments, such as Figure 1As shown, a through hole 14b is also provided on the fourth side wall 14 to connect the installation space 10a with the outside. The through hole 14b is located on the outer periphery of the detection port 14a. The manufacturing machine can clamp the housing 10 through the through hole 14b during the manufacturing of the housing 10.

[0054] According to some embodiments of this utility model, such as Figure 1 As shown, at least a portion of the edge of the detection port 14a on the fourth sidewall 14 is provided with a stop portion 141. The stop portion 141 is adapted to deform and abut against the sensor surface. Specifically, the stop portion 141 can be an elastic structure. When the sensor is installed from the mounting port 10b into the mounting space 10a, the stop portion 141 contacts the sensor and is triggered to deform. The deformed stop portion 141 applies force to the sensor to abut against the sensor surface facing the fourth sidewall 14, causing the sensor to tend to move towards the third sidewall 13. At the same time, the third sidewall 13 also abuts against the sensor surface, so that the sensor is clamped and limited within the mounting space 10a by the stop portion 141 and the third sidewall 13, thus realizing the installation of the sensor. When the sensor can no longer be pushed into the mounting space 10a, it indicates that the sensor is installed in place. When the sensor is disassembled, the operator only needs to pull to remove the sensor clamped between the stop portion 141 and the third sidewall 13, making the operation simple and convenient.

[0055] In some embodiments, the distance between the stop portion 141 and the third sidewall 13 in the third direction is slightly smaller than the thickness of the sensor in the third direction, and the stop portion 141 and the third sidewall 13 can clamp and limit the sensor within the mounting space 10a. Further, the distance between the stop portion 141 and the third sidewall 13 in the third direction is 10.7 mm, which is slightly smaller than the thickness of the sensor in the third direction of 11.3 mm.

[0056] Furthermore, a portion of the sensor's structure protrudes from the third sidewall 13 and the fourth sidewall 14 in the second direction, facilitating operator access to the sensor and enabling convenient disassembly and maintenance.

[0057] According to some embodiments of this utility model, the stop part 141 is interference-fitted with the sensor, and the interference amount of the interference fit ranges from 0.4mm to 0.8mm. Here, the interference fit between the stop part 141 and the sensor ensures that the stop part 141 and the third side wall 13 clamp and compress the sensor, thereby limiting and fixing the sensor in the housing 10. The interference amount of the interference fit should not be too large, as this would make it difficult to install the sensor into the installation space 10a and also pose a risk of sensor damage. The interference amount of the interference fit should also not be too small, as this would cause the sensor to be unstable in the installation space 10a, and the sensor would be at risk of shaking or falling off. Therefore, the interference amount of the interference fit between the stop part 141 and the sensor ranges from 0.4mm to 0.8mm, and preferably, the interference amount of the interference fit between the stop part 141 and the sensor is 0.6mm.

[0058] According to some embodiments of this utility model, such as Figures 1-3 As shown, a fixing part 113 is provided on the surface of the first sidewall 11 away from the second sidewall 12 in a first direction. A first hole 1131 is provided on the fixing part 113, which is suitable for fasteners to pass through so that the fasteners connect the sensor mounting box 1 to the external structure. Specifically, the sensor mounting box 1 can be mounted on other structures of the air handling equipment through the fixing part 113, and a second hole can be provided on the structure. Fasteners pass through the first hole 1131 and the second hole respectively to mount the housing 10 on the structure.

[0059] According to some embodiments of this utility model, such as Figure 2 As shown, the fixing part 113 is also provided with a positioning protrusion 1132, which is adapted to cooperate with the positioning groove of the external structure. Specifically, the sensor mounting box 1 can be installed on other structures of the air handling equipment, and the positioning groove can be opened on the structure. The positioning protrusion 1132 cooperates with the positioning groove to position the sensor mounting box 1 on the structure. It can work with the fastener to achieve the anti-rotation design of the housing 10, prevent the housing 10 from rotating around the fastener due to the single fastener fixing, and also reduce the number of fasteners, thereby reducing the number of parts of the sensor mounting box 1.

[0060] Furthermore, the positioning protrusion 1132 can be rectangular, elliptical, or other non-circular structures. During the process of the fixing part 113 cooperating with other structures of the air handling equipment, the positioning protrusion 1132 can be first engaged with the positioning groove of the structure to pre-position the housing 10 on the structure, so as to facilitate the subsequent installation of fasteners. The non-circular structure of the positioning protrusion 1132 can prevent the housing 10 from swinging during the pre-positioning process, so that the first hole 1131 and the second hole are aligned, which facilitates the installation of fasteners. In some specific embodiments, the positioning protrusion 1132 can be cross-shaped.

[0061] The air handling equipment according to this utility model is briefly described below.
