Abstract
Description
Technical Field
[0001] This application relates to the field of intelligent constant temperature and humidity detection technology, and more specifically, to an intelligent constant temperature and humidity detection device. Background Technology
[0002] With the rapid development of industrial production, precision instrument storage, biomedicine, and cultural relic preservation, the demand for precise control of environmental temperature and humidity is becoming increasingly urgent. Intelligent constant temperature and humidity monitoring devices, as core environmental control equipment, integrate high-precision sensors, intelligent control systems, and efficient temperature and humidity adjustment modules to monitor and dynamically adjust temperature and humidity parameters within the enclosure in real time, ensuring the stability and consistency of target environmental parameters. However, existing technologies have revealed key defects during long-term operation: flawed sealing door design leads to insufficient sealing performance, becoming a core bottleneck restricting the accuracy of temperature and humidity control. Specifically, traditional devices often use single-layer rubber strips or simple magnetic structures for their sealing doors. Due to factors such as material aging, mechanical wear, and uneven pressure distribution, gaps easily form between the door and the enclosure. Especially under frequent opening and closing or high humidity environments, the sealing strip is prone to deformation and hardening, allowing outside air to continuously infiltrate and disrupting the temperature and humidity balance within the enclosure. Utility Model Content
[0003] To overcome the above shortcomings, this application provides an intelligent constant temperature and humidity detection device to solve the problem that poor sealing of the sealing door of existing intelligent constant temperature and humidity detection devices can lead to the entry of outside air and affect the accuracy of temperature and humidity control.
[0004] To achieve the above objectives, the technical solution adopted by this utility model to solve its technical problem is as follows:
[0005] An intelligent constant temperature and humidity testing device includes an intelligent constant temperature and humidity testing machine body and a sealing door hinged to the opening of the intelligent constant temperature and humidity testing machine body. The sealing door is characterized by: a sealing plate installed inside, which is sealed to the opening of the intelligent constant temperature and humidity testing machine body; an flared groove matching the sealing plate opening at the opening of the intelligent constant temperature and humidity testing machine body; the inner wall of the flared groove being sealed to the side wall of the sealing plate; a rubber block integrally formed on the back of the sealing plate; the rubber block matching the inner wall of the testing area of the intelligent constant temperature and humidity testing machine body; and a secondary sealing mechanism at the contact point between the rubber block and the intelligent constant temperature and humidity testing machine body.
[0006] Furthermore, the sealing plate is installed on the back of the sealing door by four internal bolts, and the outer wall is sealed to the inner wall of the flared groove.
[0007] Furthermore, the sealing plate and the rubber block are made of rubber material, and a hard plate is pre-cast inside them and they are integrally formed. The sealing plate and the rubber block are respectively sealed and connected to the flared groove and the inner wall of the detection area of the intelligent constant temperature and humidity testing machine body.
[0008] Furthermore, the flared groove and the inner wall of the intelligent constant temperature and humidity testing machine form an inner stepped shape, which matches the outer stepped shape formed by the sealing plate and the outer wall of the rubber block.
[0009] Furthermore, the outer wall of the rubber block is sealed and fitted to the inner wall of the detection space of the intelligent constant temperature and humidity testing machine body through the flared groove.
[0010] Furthermore, the secondary sealing mechanism includes a raised strip and a groove. The raised strip is integrally formed on the inner wall of the intelligent constant temperature and humidity testing machine body, and the groove is formed on the side wall of the rubber block. The outer wall of the raised strip is sealed to the inside of the groove.
[0011] Furthermore, the intelligent constant temperature and humidity testing machine body has four brakeable universal wheels fixed to the four corner bolts at the bottom.
[0012] Furthermore, the intelligent constant temperature and humidity testing machine body has four support feet threaded on its bottom, and the four support feet can be flush with the bottom of the four brakeable universal wheels.
[0013] This utility model has the following beneficial effects:
[0014] 1. This utility model achieves a physical barrier seal by installing a sealing plate on the back of the sealed door, which forms an inner stepped interlocking structure with the flared groove at the opening of the testing machine body. The outer wall of the sealing plate is tightly fitted with the inner wall of the flared groove, effectively preventing outside air from seeping in through the gaps in the door body and avoiding temperature and humidity fluctuations caused by air flow. In addition, a raised strip and groove are added at the joint between the rubber block and the inner wall of the testing machine body to form a reinforced secondary sealing mechanism. Through the dual action of mechanical interlocking and elastic deformation of the rubber, tiny gaps are further filled. Even if the sealing plate and flared groove undergo slight deformation due to long-term use, the secondary sealing mechanism can still achieve dynamic compensation through the elastic deformation of the rubber block, ensuring long-term stable sealing performance.
[0015] 2. This utility model adopts a composite structure with a rubber material embedded with a hard plate, which retains the high elasticity and sealing performance of rubber, and enhances the deformation resistance of the sealing plate through the hard plate, thus avoiding sealing failure caused by frequent opening and closing of the door.

[0022] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.
[0023] Example:
[0024] Please see Figure 1 , Figure 2 An intelligent constant temperature and humidity testing device includes an intelligent constant temperature and humidity testing machine body 1 and a sealing door 2 hinged and fixed at the opening of the intelligent constant temperature and humidity testing machine body 1; four brakeable universal wheels 7 are fixed at the four corner bolts at the bottom of the intelligent constant temperature and humidity testing machine body 1; and four support feet 8 are threadedly installed at the bottom of the intelligent constant temperature and humidity testing machine body 1.
[0025] The intelligent constant temperature and humidity testing machine body 1 is a closed box structure, the internal space of which is used to create and control a constant temperature and humidity environment. The size and shape of the intelligent constant temperature and humidity testing machine body 1 are designed according to specific testing requirements. The intelligent constant temperature and humidity testing machine body 1 is internally equipped with components such as temperature and humidity sensors, heaters, coolers, humidifiers, and dehumidifiers to control the temperature and humidity environment within the box. The intelligent constant temperature and humidity testing machine body 1 utilizes existing technology in this field, and therefore will not be described in detail.
[0026] The sealed door 2 is hinged and fixed to the opening of the intelligent constant temperature and humidity testing machine body 1 via hinges. The hinges can be external or concealed to ensure that the sealed door 2 can be opened and closed smoothly. The sealed door 2 can be equipped with a locking mechanism, such as a door lock or door latch, to ensure that the sealed door 2 remains tightly closed when closed. A handle can be installed on the outer wall of the sealed door 2 for the convenience of operators to open and close the door.
[0027] The brakeable omnidirectional wheel 7 consists of a wheel body and an omnidirectional wheel frame. The omnidirectional wheel frame allows the wheel body to rotate 360 degrees in the horizontal plane, enabling the intelligent constant temperature and humidity testing machine body 1 to move easily in any direction. Each omnidirectional wheel 7 is equipped with a braking mechanism to secure the wheel. The braking mechanism typically includes a brake pedal and a locking device. When the brake pedal is pressed, the locking device locks the wheel, preventing it from rotating. The omnidirectional wheel 7 contains bearings to reduce friction and ensure smooth wheel rotation.
[0028] The support foot 8 consists of a threaded rod and a base. The top of the threaded rod is installed at one of the four positions on the bottom of the intelligent constant temperature and humidity testing machine body 1 through threaded holes. The base is usually circular and provides a stable support surface. The height of the support foot 8 can be adjusted by rotating the threaded rod. The length of the threaded rod is designed according to the required adjustment range. The base of the support foot 8 can be designed with an anti-slip structure, such as adding anti-slip texture, to enhance the stability of the equipment.
[0029] The system utilizes the combination of the brakeable caster wheel 7 and the support foot 8. When the intelligent temperature and humidity testing machine body 1 needs to be moved, the support foot 8 is rotated up, allowing the machine body 1 to be supported by the brakeable caster wheel 7. The movement and fixation of the machine body 1 can be controlled by operating the braking mechanism. Once the machine body 1 reaches the designated position, the support foot 8 is rotated down, aligning it with the bottom of the brakeable caster wheel 7 to jointly support the equipment. At this point, the brake pedal can be depressed to lock the brakeable caster wheel 7, ensuring the equipment remains stable.
[0030] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4An intelligent constant temperature and humidity testing device includes a sealing door 2 with a sealing plate 3 installed inside, which is sealed to the opening of the intelligent constant temperature and humidity testing machine body 1. The opening of the intelligent constant temperature and humidity testing machine body 1 has a flared groove 4 that matches the sealing plate 3. The inner wall of the flared groove 4 is sealed to the side wall of the sealing plate 3. A rubber block 5 is integrally formed on the back of the sealing plate 3. The rubber block 5 matches the inner wall of the testing area of the intelligent constant temperature and humidity testing machine body 1. A secondary sealing mechanism 6 is provided at the contact point between the rubber block 5 and the intelligent constant temperature and humidity testing machine body 1. The sealing plate 3 is installed on the back of the sealing door 2 by four internal bolts 31. The secondary sealing mechanism 6 includes a raised strip 61 and a groove 62.
[0031] The sealing plate 3 has a plate-like structure, and its dimensions match the inner wall dimensions of the flared groove 4. The sealing plate 3 is installed on the back of the sealing door 2 by four internal bolts 31. The four internal bolts 31 are located at the four corners of the sealing plate 3, and are threaded into pre-drilled holes on the back of the sealing door 2 to ensure that the sealing plate 3 is firmly fixed to the sealing door 2. In addition, the outer ends of the internal bolts 31 are recessed into the interior of the sealing plate 3.
[0032] The flared groove 4 is a rectangular cross-section groove structure whose length and width match the outer wall of the sealing plate 3, while its depth is determined according to the sealing requirements. The inner wall of the flared groove 4 is tightly fitted to the outer wall of the flared groove 4, forming the first-level seal.
[0033] Among them, the tight fit between the outer wall of the rubber block 5 and the inner wall of the detection space of the intelligent constant temperature and humidity testing machine body 1, as well as the secondary seal formed with the protruding strip 61, significantly enhance the sealing effect of the equipment.
[0034] The sealing plate 3 and the rubber block 5 are integrally molded together to form a single component. This integral molding method enhances the connection strength between the two, preventing separation or detachment during use. During the integral molding process of the sealing plate 3 and the rubber block 5, a rigid plate is pre-cast inside. Located within the sealing plate 3 and the rubber block 5, the rigid plate provides support for them and prevents excessive deformation under pressure. The size and shape of the rigid plate match the internal space of the sealing plate 3 and the rubber block 5.
[0035] Among them, the outer stepped shape formed by the sealing plate 3 and the outer wall of the rubber block 5, and the inner stepped structure formed by the flared groove 4 and the detection space of the intelligent constant temperature and humidity testing machine body 1, the outer stepped shape and the inner stepped shape are matched, and this stepped design enhances the interlocking force and sealing effect between the two.
[0036] The secondary sealing mechanism 6 enhances the sealing performance between the outer wall of the rubber block 5 and the inner wall of the detection space of the intelligent constant temperature and humidity testing machine body 1, forming a third-level seal. The raised strip 61 is a strip-shaped structure, arranged around the inner wall of the intelligent constant temperature and humidity testing machine body 1, with its height and width determined according to sealing requirements. The surface of the raised strip 61 can be polished to improve its surface smoothness and sealing performance. The groove 62 is formed in the area where the side wall of the rubber block 5 fits against the inner wall of the intelligent constant temperature and humidity testing machine body 1, ensuring that the groove 62 can tightly fit with the raised strip 61. When the sealing door 2 is closed, under pressure, the groove 62 on the side wall of the rubber block 5 tightly fits against the raised strip 61 on the inner wall of the intelligent constant temperature and humidity testing machine body 1. This sealing method further enhances the sealing performance of the equipment, preventing outside air from entering the equipment. The secondary sealing mechanism 6 can also compensate for the sealing deviation between the sealing plate 3 and the rubber block 5 and the inner wall of the intelligent constant temperature and humidity testing machine body 1 to a certain extent, ensuring the sealing performance of the equipment.
[0037] The working principle of this intelligent constant temperature and humidity testing device is as follows: When the sealing door 2 is closed, the outer wall of the sealing plate 3 fits tightly against the inner wall of the flared groove 4, forming a first-level seal. The outer wall of the rubber block 5 fits tightly against the inner wall of the detection space of the intelligent constant temperature and humidity testing machine body 1 through the flared groove 4, forming a second-level seal. At the same time, the groove 62 on the side wall of the rubber block 5 engages tightly with the protruding strip 61 on the inner wall of the intelligent constant temperature and humidity testing machine body 1, enhancing the sealing effect of the second-level seal and forming a third-level seal, namely the second-level sealing mechanism 6. This triple sealing structure effectively solves the problem of poor sealing of the sealing door causing outside air to enter the interior of the intelligent constant temperature and humidity testing machine body 1, ensuring a constant temperature and humidity environment inside.
[0038] It should be noted that the specific model and specifications of the intelligent constant temperature and humidity testing machine body 1 and the brakeable universal wheel 7 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.
[0039] The power supply and principle of the intelligent constant temperature and humidity testing machine body 1 are clear to those skilled in the art, and will not be described in detail here.
[0040] It will be apparent to those skilled in the art that this application is not limited to the details of the exemplary embodiments described above, and that this application can be implemented in other specific forms without departing from the spirit or essential characteristics of this application. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this application is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this application. No reference numerals in the claims should be construed as limiting the scope of the claims.
