Description

Technical Field

[0001] This invention relates to the field of temperature measurement device technology, and in particular to a detachable and cleanable oven thermometer. Background Technology

[0002] Accurate temperature monitoring within an oven (especially a charcoal oven) is crucial for ensuring food quality during cooking. Traditional oven temperature sensors often use fixed probes, which are constantly exposed to high temperatures, oil fumes, and carbon buildup. Oil and charcoal residue easily accumulate on their surfaces, affecting temperature sensing accuracy and potentially causing sluggish response or damage. Furthermore, the fixed structure makes cleaning and maintenance extremely inconvenient, often requiring shutdown and partial disassembly of the oven body, resulting in cumbersome operations and reduced efficiency.

[0003] In existing technologies, some detachable thermometer designs have emerged, allowing users to remove the probe for cleaning. However, these designs typically suffer from difficulties in alignment during disassembly and assembly, and are prone to loosening or angular misalignment after installation, affecting temperature measurement stability. Furthermore, simple disassembly does not address the need for rapid and effective self-cleaning of the probe before and after each use; users still require frequent manual deep cleaning, resulting in a relatively heavy maintenance burden.

[0004] Therefore, there is an urgent need for an oven temperature measuring device that can be quickly and reliably disassembled and assembled, and can automatically perform basic cleaning of the temperature probe during the disassembly and assembly process, so as to improve the accuracy of temperature measurement, ease of use and equipment maintenance efficiency. Summary of the Invention

[0005] In order to overcome the shortcomings of existing oven thermometers, such as easy contamination of the probe, inconvenience of cleaning and maintenance, difficulty in disassembly and assembly, and easy loosening or inaccurate alignment after installation, this invention provides a detachable and cleanable oven thermometer.

[0006] The technical solution is as follows: A detachable and cleanable oven thermometer includes a mounting plate, a base, an extension cylinder, a docking cylinder, a temperature probe, a buckle, a locking spring, a cleaning rotating cylinder, a conical ring, a correction component, and a driving cleaning component. The mounting plate is used for fixed assembly with the oven wall. The base is mounted on the mounting plate and has a hollow cavity structure. The extension cylinder is integrally connected to its right side wall. An arc-shaped elongated hole is provided on the mounting plate, through which the extension cylinder passes and extends into the oven cavity. The docking cylinder is a hollow cylindrical structure with both ends connected. The temperature probe is fixedly installed inside the docking cylinder and can be detachably inserted into the base through the docking cylinder. On the base, four mounting slots are evenly spaced along the circumference on the outer right side of the docking cylinder. Each mounting slot is rotatably connected with a buckle. A locking spring is installed between the bottom of the buckle and the bottom wall of the mounting slot. Four through slots are correspondingly opened along the circumference on the outer side of the base. The buckles and slots form a snap-fit ​​relationship. A cleaning cylinder is rotatably connected inside the extension cylinder. The right end of the cleaning cylinder extends out to the right port of the extension cylinder and is connected to a conical ring. The conical ring forms a clearance sliding fit with the detection rod of the temperature probe and is used to scrape and clean the surface of the detection rod. A correction component is installed inside the base, and a driving cleaning component is configured on the cleaning cylinder.

[0007] As a further preferred option, the outer surface of the temperature probe's detection rod is coated with a high-temperature resistant, non-stick coating.

[0008] As a further preferred option, the conical ring is made of ceramic material.

[0009] As a further preferred embodiment, the correction assembly includes a sliding disc, a compression spring, arc-shaped inclined plates, and locking blocks. The sliding disc is slidably assembled inside the base. Four arc-shaped inclined plates are fixedly connected at equal intervals along the circumference of the left side wall of the sliding disc. The left side wall of the arc-shaped inclined plates is designed as a guide inclined surface structure, and a reference groove is formed between adjacent arc-shaped inclined plates. The circumferential position of the reference groove corresponds one-to-one with the position of the locking slot on the base. A compression spring is connected between the right side wall of the sliding disc and the right end wall of the inner cavity of the base. Four locking blocks are fixedly connected at equal intervals along the circumference of the right side wall of the docking cylinder. The locking blocks form a contact guiding engagement with the guide inclined surface of the arc-shaped inclined plates, and at the same time form a locking positioning engagement with the reference groove.

[0010] As a further preferred embodiment, the drive cleaning assembly includes a ring frame, balls, and a ring. The ring frame is connected to the right side wall of the sliding disk. Receiving holes are opened on both sides of the inner wall of the ring frame, and balls are hinged in each receiving hole. The outer wall of the cleaning drum has a threaded groove, and the balls are embedded in the threaded groove to form a rolling fit. A ring is fixed to one end of the inner wall of the ring frame near the conical ring, and the ring forms a clearance sliding fit with the detection rod of the temperature probe.

[0011] As a further preferred option, the bottom of the cleaning drum is provided with three drain holes spaced apart along the axial direction, and the bottom of the extension drum is provided with a corresponding through-hole, with the drain holes and through-holes positioned correspondingly.

[0012] As a further preferred option, it also includes protruding rods. Four protruding rods are connected circumferentially at intervals on the outer periphery of the left side wall of the base that fits against the end face of the docking cylinder. Positioning holes are opened at the corresponding positions of the protruding rods on the right side wall of the docking cylinder, and the protruding rods and positioning holes form a snap-fit ​​relationship.

[0013] As a further preferred embodiment, it also includes fastening bolts, locking bolts, nuts, and arc-shaped baffles. A through hole is provided on one side of the arc-shaped elongated hole on the mounting plate, and an arc-shaped groove is provided on the other side. Mounting holes are provided on both sides of the base. Fastening bolts are inserted into the mounting holes on the base corresponding to the through holes and are fixed in the through holes. Locking bolts are inserted into the mounting holes on the base corresponding to the arc-shaped grooves and slide in a sliding fit with the arc-shaped grooves. Nuts are screwed to the ends of both the fastening bolts and the locking bolts. An arc-shaped baffle is fixed to the right side wall of the mounting plate behind the arc-shaped grooves to provide guidance and limit for the sliding of the locking bolts.

[0014] As a further preferred option, it also includes a retaining ball and a return spring. Several retaining holes are spaced apart on the mounting plate at the position corresponding to the front of the arc-shaped slide groove. A slide groove is provided on the rear side wall of the base at the position corresponding to the retaining holes. The retaining ball is slidably assembled in the slide groove, and a return spring is connected between the retaining ball and the bottom wall of the slide groove cavity. The retaining ball and the retaining hole form a retaining engagement relationship.

[0015] The present invention has the following advantages: 1. Through the elastic snap-fit ​​structure of the buckle and the slot, combined with the guiding cooperation of the arc-shaped inclined piece and the card block in the correction component, the docking cylinder can automatically correct the angle when inserted, ensuring that the buckle and the slot are accurately aligned. This design simplifies the installation operation, avoids installation difficulties caused by angle deviation, and improves the efficiency and reliability of disassembly and assembly.

[0016] 2. During the insertion and removal of the temperature probe, the driving cleaning component drives the cleaning drum and conical ring to rotate in both directions. The narrow opening of the conical ring scrapes away carbon deposits and impurities on the surface of the detection rod, while the circular ring further wipes away residual dirt. At the same time, impurities can be discharged through the drain hole, realizing online cleaning of the temperature probe and reducing the frequency of manual maintenance.

[0017] 3. With the help of the arc-shaped sliding groove, locking bolt and retaining ball structure, the height of the base and the extension cylinder can be finely adjusted to realize multi-level adjustment of the temperature probe detection position. The retaining ball and the locking hole lock the adjustment position to adapt to the temperature measurement needs of different height areas in the oven and improve the adaptability of the device.

[0018] 4. The precise positioning of the mounting plate and the built-in design of the extension tube ensure that the detection rod of the temperature probe is aligned with the center of the roasting area. After assembly, the structure is stable, and the temperature probe can stably collect temperature signals throughout the process, providing operators with accurate information to adjust the ventilation of the charcoal fire and ensuring uniform and stable roasting temperature.

Detailed Implementation

[0034] Example 1: A detachable and cleanable oven thermometer, such as Figures 1-11As shown, the device includes a mounting plate 1, a base 102, an extension cylinder 103, a docking cylinder 104, a temperature probe 105, a buckle 106, a locking spring 108, a cleaning rotating cylinder 201, a conical ring 205, a correction assembly, and a driving cleaning assembly. The mounting plate 1 serves as the main support component of the device and is used for fixed assembly with the oven wall. The base 102 is detachably mounted on the mounting plate 1. The base 102 has a hollow cavity structure, with its right side wall integrally formed and connected to the hollow extension cylinder 103. An arc-shaped elongated hole 602 is provided in the middle of the mounting plate 1. Part of the base 102 is attached to the outer wall of the mounting plate 1, and part of the extension cylinder 103 passes through the arc-shaped elongated hole 602 and extends into the inner cavity of the oven. To achieve the built-in arrangement of the temperature measuring end, the docking cylinder 104 is a hollow cylindrical structure with both ends through. The temperature measuring probe 105 is fixed inside the docking cylinder 104, and the detection rod of the temperature measuring probe 105 extends along the right end of the docking cylinder 104. The temperature measuring probe 105 is detachably inserted into the base 102 through the docking cylinder 104, so that the detection rod of the temperature measuring probe 105 extends into the oven through the inner cavity of the base 102 and the extension cylinder 103 to complete the temperature signal acquisition operation. Four mounting slots are evenly spaced along the circumference on the outer right side of the docking cylinder 104. Each mounting slot is rotatably connected to a buckle 106 by a shaft pin. A locking spring 108 is installed between the bottom of the buckle 106 and the bottom wall of the mounting slot. Under the natural elastic force, the buckle 106 initially extends at an angle. Four through slots 107 are correspondingly provided circumferentially on the outer side of the base 102. When the docking cylinder 104 axially extends into the inner cavity of the base 102, the angled end face of the buckle 106 forms a pressing fit with the inner wall of the base 102, causing the buckle 106 to retract around the pivot pin into the mounting groove until the buckle 106 is axially aligned with the slot 107. The locking spring 108 then elastically resets and drives the buckle 106 to pop outward and engage with the slot 107, achieving a detachable fixed assembly between the docking cylinder 104 and the base 102. A cleaning rotating cylinder 201 is rotatably connected inside the extending cylinder 103. This cleaning rotating cylinder 201 is open at both ends. The hollow cylinder has an extension tube 103 extending from its right end, which is integrally connected to a conical ring 205. The conical ring 205 adopts a variable diameter structure design with a wider left end and a narrower right end. The inner diameter of its narrow end is adapted to the outer diameter of the detection rod of the temperature probe 105, forming a clearance sliding fit, which is used to scrape and clean the surface of the detection rod. The base 102 is equipped with a correction component, which is used to automatically correct the circumferential angle of the temperature probe 105 during the advancement process, ensuring that the buckle 106 and the slot 107 are accurately aligned. The cleaning drum 201 is equipped with a driving cleaning component, which drives the cleaning drum 201 and the conical ring 205 to rotate synchronously through power transmission, so as to achieve dynamic cleaning of the detection rod surface of the temperature probe 105.

[0035] The outer surface of the probe 105 is coated with a high-temperature resistant, non-stick coating. This coating effectively reduces the adhesion of grease and carbon deposits to the probe surface, making cleaning easier and improving the long-term stability and temperature response speed of the probe 105 in high-temperature and high-pollution environments. The conical ring 205 is made of high-hardness, wear-resistant ceramic material. The ceramic material is hard, high-temperature resistant, and chemically stable. Its narrow end can effectively remove stubborn carbon deposits during the scraping and cleaning process with minimal wear, ensuring long-term cleaning effectiveness and reliability.

[0036] like Figure 3 and Figures 7-9 As shown, the correction assembly includes a sliding disc 301, a compression spring 302, an arc-shaped inclined plate 303, and a locking block 304. The sliding disc 301 is slidably mounted inside the base 102 in the left-right direction. Four arc-shaped inclined plates 303 are welded at equal intervals along the circumference on the left side wall of the sliding disc 301. The left side wall of the arc-shaped inclined plate 303 is designed as a guide inclined surface structure. A reference groove is formed between adjacent arc-shaped inclined plates 303. The circumferential position of the reference groove corresponds one-to-one with the position of the locking groove 107 on the base 102. A compression spring 302 is connected between the right side wall of the sliding disc 301 and the right end wall of the inner cavity of the base 102. Four locking blocks 304 are fixedly connected at equal intervals along the circumference on the right side wall of the docking cylinder 104. The locking blocks 304 form a contact guiding fit with the guide inclined surface of the arc-shaped inclined plate 303, and at the same time form a locking positioning fit with the reference groove.

[0037] like Figures 7-11 As shown, the driving cleaning assembly includes a ring frame 202, ball bearings 204, and a circular ring 206. The ring frame 202 is integrally formed on the right side wall of the sliding disk 301. The inner wall of the ring frame 202 has receiving holes on both the upper and lower sides. Each receiving hole is fitted with a ball bearing 204 through a hinge structure. The outer wall of the cleaning drum 201 has a threaded groove 203. The ball bearing 204 is embedded in the threaded groove 203 and forms a rolling fit. The inner wall of the ring frame 202 is fixed to one end near the conical ring 205. The inner diameter of the circular ring 206 is adapted to the size of the detection rod of the temperature probe 105, forming a clearance sliding fit, which is used to wipe and clean the surface of the detection rod.

[0038] Before this device is put into use, a preset installation position is first opened on the oven wall. This installation position must correspond to the roasting center area of ​​the charcoal basin in the oven so that the temperature probe 105 can accurately collect the temperature of the roasting area. Then, the device is pre-assembled: the mounting plate 1 is fixedly assembled to the oven installation position with fasteners, and the base 102 is detachably assembled to the mounting plate 1, so that the extension cylinder 103 on the base 102 extends into the oven cavity through the arc-shaped elongated hole 602. The main body of the base 102 is located outside the oven, and the inner cavities of the base 102 and the extension cylinder 103 are in communication with the oven cavity. The temperature probe 105 and the docking cylinder 104 adopt an integrated assembly structure. The temperature probe 105 is fixedly installed inside the docking cylinder 104 to form a temperature measurement execution unit. When measuring... During the oven operation, the operator holds the docking cylinder 104 and aligns the probe 105 with the left opening of the base 102, pushing it axially along the inner cavity of the base 102. The probe passes sequentially through the base 102, the ring 206 of the ring frame 202, the cleaning drum 201, and the conical ring 205, finally extending to the baking area inside the oven cavity. During this process, the locking block 304 moves axially synchronously with the docking cylinder 104, contacting the guide slope of the arc-shaped inclined plate 303 and applying axial thrust, driving the sliding plate 301 and the ring frame 202 to move to the right along the base 102. The compression spring 302 is compressed and undergoes elastic deformation. During this process, the ring frame 202 engages with the spiral drive of the ball bearing 204 and the threaded groove 203 on the outer wall of the cleaning drum 201, driving the cleaning drum... The cylinder 201 rotates around its own axis inside the protruding cylinder 103, thereby driving the conical ring 205 and the circular ring 206 to rotate synchronously. The conical ring 205, with its variable diameter structure (wider on the left and narrower on the right), performs pre-cleaning of the surface of the detection rod, scraping off dust, dirt, and other impurities adhering to the surface. The circular ring 206 rotates in contact with the surface of the detection rod, achieving initial wiping and cleaning of the surface. As the sliding disk 301 moves to its axial limit position, the locking block 304, under the continuous pushing force, generates circumferential displacement along the guide slope of the arc-shaped inclined plate 303. The operator can adaptively rotate the docking cylinder 104 with this circumferential force, driving the docking cylinder 104, the temperature probe 105, and the buckle 106 to synchronously perform circumferential fine adjustments, achieving automatic correction of the circumferential position of the buckle 106. During the process of entering the inner cavity of the base 102, the latch 106, due to its inclined posture, is squeezed against the inner wall of the base 102 and rotates around the pivot pin to a horizontally retracted state. Simultaneously, the locking spring 108 is compressed, ensuring the smooth axial advancement of the docking cylinder 104. When the locking block 304 rotates to disengage from the guide slope of the arc-shaped inclined plate 303, the circumferential position of the latch 106 is completely aligned with the slot 107 on the base 102. At the same time, the locking block 304 and the reference groove between the adjacent arc-shaped inclined plate 303 form a locking position, achieving precise calibration of the advancement angle of the temperature probe 105. At this point, the locking spring 108 elastically resets, driving the latch 106 to rotate in the opposite direction around the pivot pin to its initial inclined state, forming a firm locking with the slot 107, completing the rapid positioning and installation of the docking cylinder 104 and the temperature probe 105.The temperature probe 105 can initiate real-time temperature measurement. After the charcoal in the oven is lit, the detection rod of the temperature probe 105 collects the temperature signal inside the oven in real time. Once the temperature rises to the preset baking temperature, the food to be baked can be placed in. The temperature probe 105 remains in a fixed assembly state throughout the process, continuously feeding back the temperature data inside the oven. The operator can adjust the ventilation volume of the charcoal fire according to temperature fluctuations to ensure a stable baking temperature inside the oven.

[0039] When the temperature probe 105 needs to be disassembled for maintenance, repair, or deep cleaning, the operator presses the four clips 106 towards the mounting groove. The locking spring 108 is compressed and contracts, causing the clips 106 to disengage from the locking groove 107 of the base 102. Then, the operator holds the docking cylinder 104 and pulls the temperature probe 105 outward axially. The clips 106 move out of the inner cavity of the base 102 simultaneously with the docking cylinder 104. The locking block 304 on the docking cylinder 104 disengages from the reference groove. Under the elastic restoring force of the compression spring 302, the sliding disk 301 moves to the left along the axial direction of the base 102, driving the arc-shaped inclined... The plate 303 and the ring frame 202 are reset synchronously. The ring frame 202 drives the cleaning drum 201, the conical ring 205 and the circular ring 206 to rotate in opposite directions through the helical transmission of the ball 204 and the threaded groove 203. During the pulling out of the temperature probe 105, the narrow end of the conical ring 205 scrapes and cleans the oil and stubborn impurities attached to the surface of the rod. The circular ring 206 simultaneously wipes the cleaned surface of the rod, realizing the automatic cleaning operation of the temperature probe 105 after use. After the temperature probe 105 is completely disassembled, it can be used for subsequent maintenance and repair, or the surface of the detection rod can be further cleaned.

[0040] Example 2: Based on Example 1, such as Figure 8 and Figure 11 As shown, the bottom of the cleaning drum 201 is provided with three drain holes 401 spaced apart along the axial direction, and the bottom of the extension cylinder 103 is provided with a through port 402. The drain holes 401 and the through port 402 are positioned correspondingly. Impurities, oil stains and other dirt generated during the cleaning process of the cleaning drum 201 can flow along the inner wall of the cleaning drum 201 to the drain holes 401, and be discharged to the outside of the device through the drain holes 401 and the through port 402, so as to avoid the accumulation of dirt affecting the cleaning effect and temperature measurement accuracy.

[0041] like Figure 3 and Figure 8As shown, it also includes protruding rods 501. On the end face of the left side wall of the base 102 that is in contact with the docking cylinder 104, four protruding rods 501 are integrally formed at equal intervals along the circumference. Correspondingly, on the end face of the right side wall of the docking cylinder 104 that is in contact with the base 102, four positioning holes 502 are provided at equal intervals along the circumference. When the docking cylinder 104 and the base 102 are precisely inserted and engaged, the protruding rods 501 and the positioning holes 502 form a one-to-one corresponding engagement, realizing a secondary locking of the circumferential position of the docking cylinder 104, further improving the assembly stability. When the docking cylinder 104 is pulled out from the base 102, the positioning holes 502 and the protruding rods 501 simultaneously disengage from the engagement state, without affecting the smoothness of the disassembly operation.

[0042] like Figure 1 and Figures 12-14 As shown, it also includes fastening bolts 601, locking bolts 604, nuts 605, and arc-shaped baffles 606. A through hole is provided on one side of the arc-shaped elongated hole 602 on the mounting plate 1, and an arc-shaped groove 603 is provided on the other side. Mounting holes are provided on both the front and rear side walls of the base 102, corresponding one-to-one with the through hole and the arc-shaped groove 603 on the mounting plate 1. Fastening bolts 601 are inserted through the mounting holes on the base 102 corresponding to the through holes, achieving initial positioning at the through holes. Locking bolts 604 are inserted through the mounting holes on the base 102 corresponding to the arc-shaped groove 603, and the locking bolts 604 slide against the arc-shaped groove 603. In conjunction with the locking bolt 604 sliding along the arc-shaped groove 603, one end of the base 102 can be driven to rotate circumferentially around the fastening bolt 601, thereby driving the extension cylinder 103 to adjust its position up and down within the arc-shaped elongated hole 602, achieving fine adjustment of the angle and height of the base 102 and the extension cylinder 103. Nuts 605 are screwed to the ends of both the fastening bolt 601 and the locking bolt 604. By locking with nuts 605, the base 102 can be detachably fixed on the mounting plate 1. An arc-shaped baffle 606 is welded to the right side wall of the mounting plate 1 at the position corresponding to the rear of the arc-shaped groove 603, which is used to provide guidance and limit for the sliding of the locking bolt 604 and prevent deviation during the sliding process.

[0043] like Figures 13-14 As shown, it also includes a retaining bead 702 and a return spring 703. The mounting plate 1 has several locking holes 701 spaced apart along the arc direction at the position corresponding to the front of the arc-shaped slide groove 603. The rear side wall of the base 102 has a slide groove at the position corresponding to the locking holes 701. The retaining bead 702 is slidably assembled in the slide groove, and a return spring 703 is connected between the retaining bead 702 and the bottom wall of the inner cavity of the slide groove. In the initial state, the retaining bead 702 partially extends out of the slide groove under the elastic force of the return spring 703 and forms a locking with the corresponding locking hole 701, thereby locking the current angle and position of the base 102.

[0044] During the assembly and adjustment phase of the device, one side of the base 102 is fixed to the corresponding through hole position of the mounting plate 1 by fastening bolts 601 and nuts 605. This position serves as the rotation fulcrum of the base 102, allowing only circumferential rotation without axial sliding. The other side of the base 102 is initially assembled into the arc-shaped slide groove 603 by locking bolts 604. Nuts 605 are screwed onto the tail end of the locking bolts 604 but not fully tightened, allowing the locking bolts 604 to drive that end of the base 102 to slide circumferentially along the arc-shaped slide groove 603. This, in turn, drives the extension cylinder 103 to adjust its vertical position within the arc-shaped elongated hole 602, achieving fine-tuning of the overall angle and height of the base 102. During the angle adjustment process of the base 102... The locking bead 702 retracts into the slide groove under the squeezing force of the mounting plate 1, and the return spring 703 is compressed and deformed synchronously. When the base 102 is adjusted to the target angle, the locking bead 702 extends out of the slide groove under the elastic return force of the return spring 703 and accurately engages with the corresponding locking hole 701, realizing the positioning and locking of the height and angle of the base 102. Several locking holes 701 are arranged at intervals along the length of the arc-shaped slide groove 603, which can realize the multi-level adjustment of the height and angle of the base 102, adapting to the assembly requirements of the matching cylinder 104 and the temperature probe 105. Through this adjustment structure, the corresponding height of the detection rod of the temperature probe 105 in the oven cavity can be changed, adapting to the temperature acquisition requirements under different baking scenarios.
