Description

Technical Field

[0001] This invention relates to a thermometer, and more particularly to a thermometer for use in grilling. Background Technology

[0002] During the grilling process, especially when grilling meat, a grill thermometer is usually needed to measure the internal temperature of the meat or other ingredients in order to determine how well they are cooked.

[0003] Existing barbecue thermometers (such as the invention patent with publication number CN112964393A, which discloses a barbecue thermometer) typically include a thermometer body and a pin mounted on the thermometer body. During measurement, the pin is inserted into the interior of the barbecued meat or other food to measure its internal temperature. To protect the pin, existing barbecue thermometers usually come with a protective sleeve. However, after use, the surface of the pin often has some liquid (such as grease, meat juice, or vegetable juice) adhering to it. If the pin is inserted directly into the protective sleeve without being cleaned, these liquids will drip into the sleeve, contaminating its interior. Summary of the Invention

[0004] The purpose of this invention is to solve the problem that after use, the surface of the probe of an existing barbecue thermometer usually has some liquid adhering to it. If the probe is inserted directly into the protective sleeve without being wiped clean, this liquid will drip into the protective sleeve and cause contamination inside the sleeve. This invention provides a barbecue thermometer that can effectively solve the above problems.

[0005] The objective of this invention is achieved through the following technical solution: a thermometer for grilling, comprising a thermometer body, a pin disposed on the thermometer body, and a protective sleeve for fitting onto the pin, characterized in that: the protective sleeve is provided with a cleaning and wiping mechanism.

[0006] In this invention, the protective sleeve is provided with a cleaning and wiping mechanism. When the pin is inserted into the protective sleeve, the cleaning and wiping mechanism can clean the liquid adhering to the surface of the pin. In this way, when the pin is inserted into the protective sleeve, the liquid will not drip into the protective sleeve, and the inside of the protective sleeve will not be contaminated.

[0007] Preferably, the protective cover is made of polyethylene. Polyethylene is a non-toxic and odorless material, making it relatively safe to use.

[0008] Preferably, one end of the protective sleeve is an open end. The cleaning and wiping mechanism includes a scraping ring and a wiping device disposed inside the protective sleeve. The scraping ring is disposed on the side of the liquid collection mechanism away from the open end. The wiping device includes an annular cavity and a sliding rod disposed inside the protective sleeve. The annular cavity is disposed on the protective sleeve near the open end. A rotatable wiping ring is connected to the annular cavity. The wiping ring includes an annular shell. Several guide plate groups are disposed in the annular shell. The guide plate groups are arranged in a circular array in the annular shell. The guide plate groups are arranged radially along the annular shell. Each guide plate group consists of two opposing guide plates. A wiping component that can move radially along the annular shell is disposed between the guide plate groups. A tension spring is disposed between the end of the wiping component away from the center of the annular shell and the inner wall of the annular shell. A fixed shaft is provided on one side, and a lever is rotatably connected to the fixed shaft. The lever has a shaft hole, and the fixed shaft is connected to the shaft hole. One end of the lever contacts the end of the wiping component away from the center of the annular shell, and the other end of the lever is connected to a centrifugal counterweight. An external gear ring is provided on the circumference of the annular shell. The liquid collection mechanism also includes a gear cavity located on one side of the annular cavity. A rotatable transmission gear is provided in the gear cavity, and the transmission gear meshes with the external gear ring on the annular shell. The transmission gear has a central hole, and a protrusion is provided on the inner wall of the central hole. The sliding rod is round and has a spiral groove. The sliding rod passes through the central hole, and the protrusion is embedded in the spiral groove. One end of the sliding rod has a guide boss, and a guide groove is provided on the outer side of the protective sleeve. The guide groove is arranged along the axial direction of the protective sleeve, and the guide boss is slidably connected in the guide groove. The scraping ring and the liquid collection device are both located on the protective sleeve near the open end. The pin is inserted from the open end of the protective sleeve. Before inserting the pin into the protective sleeve, first pull the sliding rod forward, then insert the pin through the open end of the protective sleeve. During insertion, the inner side of the scraper ring is in close contact with the side of the pin, and one end of the scraper blade also contacts the side of the pin. The scraper ring scrapes off the liquid adhering to the surface of the pin, and the liquid is scraped to the position of the wiping ring. When the pin is inserted to a certain position, one end of the sliding rod presses against the thermometer body. During the subsequent insertion process, relative movement occurs between the sliding rod and the protective sleeve. As the sliding rod moves, the helical groove drives the transmission gear to rotate, which in turn drives the wiping ring to rotate. At this time, under the action of centrifugal force, the centrifugal counterweight moves one end of the lever towards the radial outer side of the annular shell, while the other end of the lever pushes the wiping component towards the center of the annular shell, so that the wiping component is in close contact with the side of the pin, and the liquid scraped off is wiped away by the rotation of the wiping component. In this way, even if the pin is inserted directly into the protective sleeve without being wiped clean, the liquid adhering to the surface of the pin will not drip into the protective sleeve, avoiding contamination inside the protective sleeve. When the pin is inserted into the position, the wiping ring stops rotating, the centrifugal force disappears, and at this time the wiping component moves away from the side of the pin and returns to its original position under the action of the tension spring.In actual use, simply replace the wiping ring or the wiping components on the wiping ring periodically.

[0009] Preferably, the wiping component includes a wiping block and a base plate, with the base plate disposed on one end of the wiping block away from the center of the annular housing.

[0010] Preferably, the wiping block is made of sponge.

[0011] Preferably, the scraper ring is made of rubber.

[0012] Preferably, a cover plate is attached to the open end face of the protective sleeve, and the cover plate is connected to the protective sleeve by screws. The cover plate is annular in shape and is detachable; the cover plate confines the wiping ring in the annular cavity; after removing the cover plate, the wiping ring can be removed from the annular cavity, thus facilitating the replacement of the wiping ring.

[0013] The beneficial effects of the present invention are as follows: In the present invention, the protective cover is provided with a cleaning and wiping mechanism. When the pin is inserted into the protective cover, the cleaning and wiping mechanism can remove the liquid adhering to the surface of the pin. In this way, when the pin is inserted into the protective cover, the liquid will not drip into the protective cover, and the inside of the protective cover will not be contaminated.

[0023] like Figures 1 to 6 As shown, a thermometer for grilling includes a thermometer body 1, a pin 2 disposed on the thermometer body 1, and a protective sleeve 3 for fitting over the pin 2. The protective sleeve 3 is made of polyethylene material. The protective sleeve 3 is provided with a cleaning and wiping mechanism for removing liquid from the surface of the pin. One end of the protective sleeve 3 is an open end, through which the pin 2 is inserted.

[0024] The cleaning and wiping mechanism includes a scraper ring 8 and a wiping device disposed inside the protective sleeve 3. The scraper ring 8 is annular in shape and made of rubber. It is located on the side of the liquid collection mechanism away from the open end. The wiping device includes an annular cavity and a sliding rod 5 disposed inside the protective sleeve 3. The annular cavity is located on the protective sleeve 3 near the open end. A cover plate 9, also annular in shape, is connected to the end face of the open end of the protective sleeve 3. The cover plate 9 is connected to the protective sleeve 3 by screws 10. A rotatable wiping ring is connected to the annular cavity. The wiping ring includes an annular housing 11, within which several guide plate assemblies are arranged in a circular array. These guide plate assemblies are radially arranged along the annular housing 11, and each guide plate assembly consists of two opposing guide plates 19. A wiping component that can move radially along the annular shell is arranged between the guide plate assemblies. A tension spring 13 is provided between the end of the wiping component away from the center of the annular shell and the inner wall of the annular shell. The wiping component includes a wiping block 12 and a base plate 20. The base plate 20 is located on the end of the wiping block 12 away from the center of the annular shell 11. The wiping block 12 is made of sponge. A fixed shaft 21 is arranged next to the wiping component. A lever 22 is rotatably connected to the fixed shaft 21. The lever 22 has a shaft hole, and the fixed shaft 21 is connected to the shaft hole. One end of the lever 22 contacts the end of the wiping component away from the center of the annular shell, and the other end of the lever 22 is connected to a centrifugal counterweight 23, which is made of iron. An external gear ring 16 is arranged in the circumferential direction of the annular shell 11. The liquid collection mechanism also includes a gear cavity, which is located on one side of the annular cavity. A rotatable transmission gear 14 is arranged in the gear cavity, and the transmission gear 14 meshes with the external gear ring 16 on the annular shell 11. The transmission gear 14 has a central hole 17, and a protrusion 15 is provided on the inner wall of the central hole 17. The sliding rod 5 is round and has a spiral groove 18. The sliding rod 5 passes through the central hole, and the protrusion 15 is embedded in the spiral groove 18. The sliding rod 5 is arranged along the axial direction of the protective sleeve 3. A guide boss 6 is provided at one end of the sliding rod, and a guide groove 7 is provided on the outer side of the protective sleeve 3. The guide groove 7 is arranged along the axial direction of the protective sleeve 3, and the guide boss 6 is slidably connected in the guide groove 7.

[0025] In this invention, a cleaning and wiping mechanism is provided on the protective sleeve. When the needle is inserted into the protective sleeve, the cleaning and wiping mechanism can clean the liquid adhering to the surface of the needle. This prevents liquid from dripping into the protective sleeve after the needle is inserted, thus avoiding contamination of the inside of the protective sleeve. The needle is inserted from the open end of the protective sleeve. Before inserting the needle into the protective sleeve, the sliding rod is pulled forward, and then the needle is inserted from the open end of the protective sleeve. During insertion, the inner side of the scraping ring is in close contact with the side of the needle, and one end of the scraper also contacts the side of the needle. The scraping ring scrapes off the liquid adhering to the surface of the needle, and the liquid is scraped to the position of the wiping ring. When the needle is inserted to a certain position, one end of the sliding rod presses against the thermometer body. During the subsequent insertion process, relative movement occurs between the sliding rod and the protective sleeve. As the sliding rod moves, the transmission gear rotates under the action of the spiral groove. The transmission gear drives the wiping ring to rotate. During operation, the centrifugal counterweight, under centrifugal force, moves one end of the lever radially outward from the annular shell, while the other end pushes the wiping component towards the center of the annular shell. This ensures the wiping component is in close contact with the side of the pin, and the rotation of the wiping component wipes away the scraped liquid. This prevents liquid adhering to the pin's surface from dripping into the protective sleeve even if the pin is not completely cleaned, thus avoiding contamination. Once the pin is fully inserted, the wiping ring stops rotating, the centrifugal force disappears, and the wiping component, under the action of a tension spring, moves away from the side of the pin and returns to its original position. In practical use, the wiping ring or the wiping component on the wiping ring should be replaced periodically.

[0026] Finally, it should be noted that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
