Description

Technical Field

[0001] This application relates to the technical field of temperature control probe auxiliary components, and in particular to a temperature controller probe cover for a cake display case. Background Technology

[0002] Cake display cases are crucial equipment for food display and preservation, requiring temperature controllers to monitor the internal temperature in real time via built-in probes. The temperature controller probe cover is an important component of the system, its core function being to protect the probe from external environmental interference, ensuring accurate and stable temperature detection. It prevents dust, moisture, oil, and other impurities from directly adhering to the probe, avoiding these factors from affecting temperature detection accuracy. Simultaneously, it can mitigate damage to the probe from external impacts and pressure, extending its lifespan and ensuring the overall normal operation of the temperature controller.

[0003] Traditional temperature controller probe protection structures use enclosed shells (such as simple plastic boxes), which can block impurities to a certain extent, but poor air circulation can easily cause temperature measurement lag; or it is difficult to balance ventilation and protection. Traditional openings are either too large, allowing dust to enter and increasing cleaning difficulty, or the layout is unreasonable, causing airflow turbulence, affecting the real-time performance and accuracy of temperature response, and the protection strength is easily insufficient due to unreasonable layout and structure. Utility Model Content

[0004] To address the challenge of balancing breathability and protection, this application provides a cover for a cake display case temperature controller probe.

[0005] The technical solution for the cake display case temperature controller probe cover provided in this application is as follows: A temperature controller probe cover for a cake display case includes a first housing and a second housing that is fixed to or detachable from the first housing. Both the first and second housings have linearly arrayed, narrow-sided elongated holes that block large dust particles. The first housing, the second housing, and the elongated holes combine to form a regular perforated and rigid protective mesh structure that facilitates air circulation. The surface of the second housing has symmetrically provided auxiliary grooves for accommodating the probe connection wire.

[0006] By adopting the above technical solution, the openability of the cover is achieved, making the cleaning, maintenance and replacement of the probe and the inside of the cover extremely convenient. The long holes form an efficient air circulation channel to ensure accurate and lag-free temperature measurement. At the same time, the narrow side generates a screening effect to achieve passive dust prevention, balancing the contradiction between breathability and protection. Under the premise of reducing weight through hollowing, the structural design ensures the overall mechanical strength and can effectively resist collisions and compression.

[0007] Preferably, a first trapezoidal block and a second trapezoidal block of the same size are fixedly connected to the two end surfaces of the second housing, and a first trapezoidal groove and a second trapezoidal groove adapted to the size of the first trapezoidal block and the second trapezoidal block are respectively opened on the two end surfaces of the first housing.

[0008] By adopting the above technical solution, the cooperation between the trapezoidal block and the trapezoidal groove plays a role in rapid preliminary positioning, guiding the two shells to accurately align and preventing reverse installation or misalignment.

[0009] Preferably, a limiting post is fixedly connected to the surface of the first trapezoidal block, and an installation groove is provided on the surface of the first housing. A limiting block for restricting the movement of the limiting post is movably connected inside the installation groove.

[0010] By adopting the above technical solution, the limiting post and the limiting block can be quickly locked and unlocked, and users can disassemble and assemble them by hand without tools, which greatly improves the convenience of operation and maintenance efficiency.

[0011] Preferably, the surface of the first housing has a limiting groove that penetrates the interior of the mounting groove and communicates with the interior of the first trapezoidal groove, and the bottom dimension of the limiting groove is adapted to the dimension of the limiting post.

[0012] By adopting the above technical solution, the limiting groove provides a precise moving path and a final locking position for the limiting post.

[0013] Preferably, the inner wall of the mounting groove is fixedly connected to a fixed column that is rotatably connected through the inside of the limiting block, and the surface of the fixed column is fitted with a torsion spring at both ends that are fixedly connected to the limiting block and the first housing, respectively.

[0014] By adopting the above technical solution, the torsion spring provides automatic rebound force for the limit block.

[0015] Preferably, a baffle is fixedly connected to one side of the surface of the limiting block.

[0016] By adopting the above technical solution, the baffle is used to limit the excessive rotation of the limit block.

[0017] Preferably, a mounting member for auxiliary support of the first housing is fixedly connected through the interior of the first housing, and the mounting member has a mounting hole inside.

[0018] By adopting the above technical solution, the entire probe cover can be securely installed in the predetermined position by fasteners such as bolts passing through the mounting holes, preventing it from loosening or falling off and ensuring long-term reliability.

[0019] Preferably, the inner wall of the first housing is arc-shaped.

[0020] By adopting the above technical solution, the smooth arc eliminates dead corners, preventing water droplets from condensing from gathering and allowing them to slide quickly down the wall surface.

[0021] In summary, this application includes at least one of the following beneficial technical effects: 1. The design of the first housing, featuring regular perforations and a vertical distribution of elongated holes (two rows of elongated holes on the front and one row on each side), ensures efficient airflow while utilizing the sieving effect of the narrow edges of the elongated holes to block large dust particles, achieving a balance between high-efficiency air permeability and passive dust prevention. Ambient temperature is rapidly transferred to the probe through convection and thermal radiation via the perforated areas. The linear layout of the elongated holes guides airflow to evenly cover the probe surface, avoiding localized temperature differences (such as heat buildup in traditional enclosed structures) and ensuring accurate temperature measurement.

[0022] 2. Through the lightweight design of the overall hollow structure, the solid frames at both ends of the first housing and the connecting ribs formed by the two rows of long holes on the front of the first housing, a rigid protective net is formed. When subjected to external forces (such as collisions or compression), the force is dispersed and transmitted through the frame and ribs to avoid stress concentration that could damage the probe, ensuring a firm connection and strong vibration resistance.

[0023] 3. This protective cover can be configured with either an integrated or a split structure. In the split structure, the second housing is detachable and features an auxiliary slot to accommodate the probe connection cable, eliminating gaps after installation and significantly reducing the path for impurities to enter. The detachable second housing allows for quick assembly and disassembly, facilitating cleaning or replacement of auxiliary slots of different sizes to accommodate probe cables of varying thicknesses, enhancing usability and ease of maintenance. The interlocking of the first and second trapezoidal blocks and slots, coupled with the snap-fit ​​structure of limiting blocks and posts, ensures a secure connection, strong vibration resistance, stable installation, and minimal displacement. Furthermore, its lightweight design makes it suitable for miniaturized, high-frequency temperature control applications. Attached Figure Description

[0026] The following is in conjunction with the appendix Figures 1-7 This application will be described in further detail.

[0027] This application discloses a temperature controller probe cover for a cake display case.

[0028] Example 1 Reference Figure 1 , Figure 2 A temperature controller probe cover for a cake display case includes a first housing 1 and a second housing 5 fixed to the first housing 1. The probe cover is integral. Elongated holes 2 are formed on the upper and outer surfaces of the first housing 1 and the surface of the second housing 5. The elongated holes 2 penetrate the interiors of both the first housing 1 and the second housing 5. The elongated holes 2 are arranged in a long linear array along the second housing 5, forming one row of ventilation holes. The elongated holes 2 are also arranged in a long linear array along the first housing 1, forming two rows of ventilation holes. Longer connecting ribs are formed between the two rows of elongated holes 2. The elongated holes 2 are narrow-sided to block large dust particles. The dust collector is composed of a first housing 1, a second housing 5, and an elongated hole 2, forming a regular hollow and rigid protective mesh structure. The hollow structure achieves overall lightweighting and efficient air circulation. Two auxiliary slots 6 are provided on the lower surface of the second housing 5. The two auxiliary slots 6 are symmetrically arranged and are used to accommodate the probe's connecting wire. In use, the probe cover composed of the first housing 1 and the second housing 5 is placed on the temperature controller probe. The probe's connecting wire extends from the auxiliary slot 6 and connects to the temperature controller. Different sizes of auxiliary slots 6 can be replaced by disassembling the second housing 5 to accommodate probe connecting wires of different thicknesses.

[0029] During use, ambient temperature is rapidly transferred to the probe via convection and thermal radiation through the perforated area. The linear layout of the elongated holes 2 guides airflow to evenly cover the probe surface, avoiding localized temperature differences and ensuring accurate temperature measurement. When subjected to external forces (such as collisions or compression), the force is dispersed and transmitted through the solid frame and ribs at the edges of the first housing 1 and the second housing 5, preventing stress concentration and damage to the probe. Simultaneously, the perforated shape physically blocks large particles of impurities (such as dust and debris), using geometric dimensional differences to prevent these particles from contacting the probe, achieving a protective logic of "hollowing out the solid." Furthermore, the overall shape, with rounded ends and a hollow center, conforms to a lightweight, high-strength design. The rounded ends disperse external impact forces (similar to the mechanics of an arch bridge, transmitting force to both sides), and the perforated area, with its reasonable hole spacing and shape (the long axis of the elongated holes 2 is perpendicular to the direction of force, enhancing bending resistance), ensures structural rigidity while reducing weight, making it suitable for scenarios involving long-term vibration and frequent installation of the temperature controller.

[0030] The first housing 1 and the second housing 5 can be made of ABS plastic, which has good high temperature resistance, UV resistance, and impact resistance, making it suitable for long-term operation in temperature controller environments. The solid frame design of the first housing 1 and the second housing 5, combined with the frame and ribs, disperses the force generated by collisions, ensuring that the housing is not easily damaged by external forces, while also improving its vibration resistance. The design of the elongated holes 2 needs to balance breathability and dustproofing. The elongated holes 2 are preferably 2mm wide, 10mm long, and 5mm apart. The linear arrangement of the elongated holes 2 allows for rapid airflow, ensuring the accuracy of the probe's temperature measurement. At the same time, the narrow edge design of the elongated holes 2 effectively blocks large dust particles from entering, improving dustproofing.

[0031] Reference Figure 1 , Figure 2 The inner ends of the first housing 1 are fixed to the outer surfaces of two mounting members 3, which penetrate the interior of the first housing 1. The mounting members 3 assist in supporting the first housing 1. When the first housing 1 is compressed, the mounting members 3 can support the entire first housing 1, preventing dents. Each mounting member 3 has mounting holes 4 inside, through which bolts can pass to fix it to the mounting plate at the mounting position. The inner wall of the first housing 1 is arc-shaped. When the cake display case is opened and closed, warm, water-vapor-rich air from outside quickly rushes into the low-temperature cabinet. When this humid air comes into contact with the probe cover surface, which remains cold due to thermal inertia, the temperature suddenly drops below the dew point temperature. The air's ability to hold water vapor decreases significantly, and excess water vapor condenses into small water droplets on the cover surface. The arc shape of the inner wall of the first housing 1 makes it easier for water droplets to move and slide off under their own weight, preventing blockage of the elongated holes 2. The increased airflow through the elongated holes 2 reduces water droplet condensation.

[0032] When the probe and its connecting wire are fixed after the first housing 1 and the second housing 5 are combined, the installer uses bolts inserted into the mounting hole 4 and through the mounting plate installed with the first housing 1 to fix it.

[0033] The implementation principle of the cake display cabinet temperature controller probe cover in this application embodiment is as follows: When in use, the first housing 1 and the second housing 5 are fixed as an integral probe cover and placed on the temperature controller probe. The probe connection line extends from the auxiliary groove 6 and connects to the temperature controller. The probe cover is fixed by inserting bolts into the mounting hole 4. Through the regular hollowing and vertical distribution of the elongated holes 2 in the first housing 1 (two rows of elongated holes 2 on the front and one row of elongated holes 2 on both sides of the first housing 1), the air circulation efficiency is ensured, and the narrow side of the elongated holes 2 is used to block large dust particles, thus achieving a combination of high-efficiency air permeability and passive dust prevention. Ambient temperature is rapidly transferred to the probe through convection and thermal radiation via the perforated area. The linear layout of the elongated holes 2 guides airflow to evenly cover the probe surface, avoiding localized temperature differences (such as heat accumulation in traditional enclosed structures) and ensuring accurate temperature measurement. The lightweight overall perforated structure and the connecting ribs formed by the solid frames at both ends of the first housing 1 and the two rows of elongated holes 2 on the front of the first housing 1 constitute a rigid protective net. When subjected to external forces (such as collisions or compression), the force is dispersed and transmitted through the frame and ribs, avoiding stress concentration that could damage the probe and ensuring a firm connection and strong vibration resistance.

[0034] Example 2 Reference Figure 3 , Figure 4 as well as Figure 5 The probe cover consists of a first housing 1 and a second housing 5 detachably fixed to the first housing 1. The probe cover is a split type, designed to be separate without altering the functionality of the integrated design. The two end surfaces of the second housing 5 are respectively fixed to the surfaces of a first trapezoidal block 7 and a second trapezoidal block 17. The first trapezoidal block 7 and the second trapezoidal block 17 are respectively located on the surfaces of the second housing 5 near the first housing 1. The first trapezoidal block 7 and the second trapezoidal block 17 have the same dimensions. The two end surfaces of the first housing 1 are respectively provided with a first trapezoidal groove 8 and a second trapezoidal groove 16. The inner wall of the first trapezoidal groove 8 is connected to the surface of the first trapezoidal block 16. The outer surface of trapezoidal block 7 is slidably connected, the size of the first trapezoidal groove 8 is adapted to the size of the first trapezoidal block 7, the inner wall of the second trapezoidal groove 16 is slidably connected to the outer surface of the second trapezoidal block 17, and the size of the second trapezoidal groove 16 is adapted to the size of the second trapezoidal block 17 to prevent the second housing 5 from shaking after installation. The top surface of the first trapezoidal block 7 is fixedly connected to the outer surface of the limiting post 11. An installation groove 9 is provided on the upper surface of the first housing 1 near the first trapezoidal block 7. The interior of the installation groove 9 is movably connected to the surface of the limiting block 14. The limiting block 14 is used to restrict the movement of the limiting post 11.

[0035] The dimensions of the first trapezoidal block 7 and the second trapezoidal block 17 are preferably: 15mm width, 10mm height, and 15° angle of the hypotenuse. The dimensions of the first trapezoidal groove 8 and the second trapezoidal groove 16 should match the dimensions of the first trapezoidal block 7 and the second trapezoidal block 17: 15mm width, 10mm height, and 15° angle, to ensure that the two parts fit tightly and are installed securely, and to avoid loosening or reverse installation.

[0036] When it is necessary to clean the inside of the first housing 1 or change the size of the auxiliary groove 6, the installer pries the limiting block 14 inside the first housing 1 to rotate the limiting block 14 and open the opening of the mounting groove 9. The installer then grasps the second housing 5 with his other hand and moves it upward. As the second housing 5 moves, it drives the first trapezoidal block 7, the limiting post 11, and the second trapezoidal block 17 upward. The first trapezoidal block 7 slides inside the first trapezoidal groove 8, and the second trapezoidal block 17 slides inside the second trapezoidal groove 16. When the limiting post 11 leaves the inside of the mounting groove 9, the installer releases the limiting block 14, and the limiting block 14 returns to its original position, thus disassembling the second housing 5. During installation, simply align the first trapezoidal block 7 with the first... The trapezoidal groove 8 and the second trapezoidal block 17 are aligned with the second trapezoidal groove 16. The first trapezoidal block 7 is inserted into the first trapezoidal groove 8, and the second trapezoidal block 17 is inserted into the second trapezoidal groove 16. When the limiting post 11 touches the limiting block 14, the side of the limiting block 14 facing the outside of the first housing 1 is inclined. Through the inclined contact and compression between the limiting post 11 and the limiting block 14, the limiting block 14 is rotated into the first housing 1 to open the opening of the mounting groove 9. The limiting post 11 enters the interior of the mounting groove 9. After the limiting post 11 stops moving, the contact between the limiting block 14 and the limiting post 11 disappears, and the limiting block 14 is reset. The inner side of the limiting block 14 near the limiting post 11 is parallel to the limiting post 11 and holds the limiting post 11 in place.

[0037] Reference Figure 6 , Figure 7 A limiting groove 10 is formed on the surface of the first housing 1. The limiting groove 10 penetrates the interior of the mounting groove 9 and communicates with the interior of the first trapezoidal groove 8. The bottom dimension of the limiting groove 10 is adapted to the dimension of the limiting post 11. The inner wall of the limiting groove 10 is slidably connected to the outer surface of the limiting post 11. Figure 7As shown, the diameter formed by the bottom end of the limiting block 14 and the limiting groove 10 is the same as the diameter of the limiting post 11. This is used to prevent the limiting post 11 from moving after it enters the limiting groove 10, thus avoiding instability after the second housing 5 is installed. The inner walls of the mounting groove 9 are fixed to both ends of the fixing post 12. The fixing post 12 passes through the bottom end of the limiting block 14. The outer surface of the fixing post 12 is rotatably connected to the inner wall of the limiting block 14. A torsion spring 13 is sleeved between the inner side of the limiting block 14 and the middle surface of the fixing post 12. The bottom end of the torsion spring 13 is fixed to the inside of the first housing 1, and the top end of the torsion spring 13 is fixed to the middle of the limiting block 14. The side of the limiting block 14 away from the limiting groove 10 is fixed to the surface of the baffle 15. The size of the baffle 15 is larger than the width of the mounting groove 9. Initially, the baffle 15 is in close contact with the inner wall of the first housing 1. The baffle 15 restricts the limiting block 14 from rotating excessively due to the elastic force of the torsion spring 13.

[0038] When the limiting post 11 is installed, it slides inside the limiting groove 10. When the limiting post 11 presses against the limiting block 14, the limiting block 14 rotates and presses against the torsion spring 13. When the limiting block 14 rotates, it drives the baffle 15 to rotate into the first housing 1. When the limiting post 11 does not press against the limiting block 14, the elastic force of the torsion spring 13 drives the limiting block 14 to rotate and reset, closing the opening between the limiting groove 10 and the mounting groove 9, preventing the limiting post 11 from leaving the interior of the mounting groove 9. The disassembly and assembly of the second housing 5 facilitates cleaning or replacement of auxiliary grooves 6 of different sizes, improving the flexibility of use and the convenience of maintenance. The insertion and engagement of the first trapezoidal block 7 and the second trapezoidal block 17 with the first trapezoidal groove 8 and the second trapezoidal groove 16, supplemented by the snap-fit ​​structure between the limiting block 14 and the limiting post 11, ensures a firm connection, strong vibration resistance, and stable installation that is not easily displaced.

[0039] The implementation principle of the temperature controller probe cover for a cake display case in this application embodiment is as follows: By designing the probe cover as a split type, during installation, the second housing 5 is inserted into the first trapezoidal groove 8 and the second trapezoidal groove 16 respectively through the first trapezoidal block 7 and the second trapezoidal block 17 to prevent the second housing 5 from being disassembled by lateral pulling. Then, the limiting block 14 is squeezed to lock the limiting post 11 to achieve fixation. During disassembly, the limiting block 14 is pried open to allow the limiting post 11 to be taken out to achieve disassembly. The second housing 5 is detachable and is provided with an auxiliary groove 6 to accommodate the probe connection wire. After installation, there is no extra gap, which fundamentally reduces the path of impurities entering. The detachable second housing 5 supports quick disassembly and assembly, facilitating cleaning or replacement of auxiliary slots 6 of different sizes, and adapting to probe wires of different thicknesses, thus improving the flexibility of use and ease of maintenance. Through the plug-in cooperation of the first trapezoidal block 7 and the second trapezoidal block 17 with the first trapezoidal slot 8 and the second trapezoidal slot 16, supplemented by the snap-fit ​​structure of the limiting block 14 and the limiting post 11, the connection is ensured to be firm, highly resistant to vibration, and stable in installation without easy displacement. At the same time, the overall weight is light, making it suitable for miniaturized, high-frequency temperature control scenarios.

Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
