Description

Technical Field

[0001] This utility model relates to the field of body temperature measurement equipment, and in particular to an infrared thermometer with a battery cover designed to prevent loss. Background Technology

[0002] Infrared thermometers are widely used in homes, hospitals, schools, and other settings due to their fast measurement speed and non-contact measurement capabilities. Current infrared thermometers typically use a removable battery cover design, requiring the cover to be completely removed from the thermometer body when changing batteries. However, this design has significant drawbacks: the small size of the battery cover makes it easy to lose during routine battery changes; especially in medical settings or when multiple people use the thermometer at home, a lost battery cover not only renders the thermometer unusable but also necessitates the purchase of a replacement, increasing costs and inconvenience. Furthermore, while some improved designs attempt to reduce the risk of loss through snap-fit ​​connections, they still do not fundamentally solve the problem of the thermometer detaching from the body after disassembly, offering limited protection against loss.

[0003] To address the shortcomings of the existing technology, this utility model proposes a physical anti-loss structure for the battery cover that is pushed open without detaching from the main body, effectively preventing the battery cover from being lost through structural design. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, this utility model provides an infrared thermometer with a battery cover to prevent loss.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] This utility model provides an infrared thermometer with a battery cover to prevent loss. It includes a thermometer body, a battery compartment on the thermometer body, and a battery cover for use with the battery compartment. The battery cover is used to seal / protect the battery compartment in conjunction with the thermometer body. A first groove is formed on the thermometer body, and the battery cover is partially housed in the first groove. The first groove is used for the battery cover to rotate and / or slide relative to the thermometer body, and the first groove is used to prevent the battery cover from detaching from the thermometer body.

[0007] Preferably, the battery cover is provided with a shaft, and the battery cover is rotatably and / or slidably disposed in the groove via the shaft. The shaft enables the battery cover to rotate and / or slide flexibly around the shaft, thereby achieving efficient opening and closing of the battery cover and improving the convenience of operation.

[0008] Preferably, there are two strip-shaped first grooves, the length of which intersects the length of the shaft. The two first grooves are located at both ends of the shaft's length direction, which limits the sliding stroke of the battery cover. The first grooves do not penetrate the thermometer body along their length direction so that the battery cover does not detach from the thermometer body. The two strip-shaped first grooves that intersect the shaft's length direction provide a specific path for the shaft's sliding. At the same time, through their non-penetrating design and the positions of both ends, the sliding range of the shaft is precisely limited, effectively controlling the sliding stroke of the battery cover, preventing the battery cover from sliding excessively and detaching from the thermometer body, ensuring that the battery cover always remains connected to the thermometer body, and guaranteeing the sealing of the battery compartment and the safety of the battery.

[0009] Preferably, the thermometer body and the battery cover are respectively provided with a first limiting member and a second limiting member. When the battery cover is in a preset position and does not slide relative to the thermometer body, the second limiting member engages with the first limiting member to prevent the battery cover from rotating relative to the thermometer body. The first limiting member and the second limiting member cooperate with each other to form an engaging structure when the battery cover is in a specific preset position and does not slide, preventing the battery cover from rotating. When the battery cover does not need to rotate, it can stabilize the position of the battery cover and avoid the battery cover from becoming loose or the battery compartment being exposed due to accidental rotation, thus ensuring the stable and closed state of the battery compartment and improving the safety of the thermometer.

[0010] Preferably, the second limiting member is located on the battery cover at the end away from the shaft, and the first limiting member is located on the thermometer body at the end away from the first groove to work in conjunction with the second limiting member. By setting the second limiting member and the first limiting member respectively at positions on the battery cover and the thermometer body that are relatively away from the shaft and the first groove, the two can accurately correspond and engage at specific positions. This optimizes the design layout of the limiting structure, improves the accuracy and reliability of the limiting, and ensures that the first limiting member and the second limiting member can effectively cooperate when limiting is required, thereby enhancing the restriction effect on the rotation of the battery cover.

[0011] Preferably, the thermometer body has a positioning protrusion located in the first groove. The positioning protrusion is located on the path of the shaft's sliding stroke. The positioning protrusion is used to limit the sliding of the battery cover relative to the thermometer body. The second limiting element is a locking protrusion, and the first limiting element is a locking groove. When the positioning protrusion clamps and limits the shaft with one end of the groove wall of the first groove, the locking protrusion is locked in the locking groove to prevent the battery cover from rotating relative to the thermometer body. After the shaft passes the positioning protrusion by sliding the battery cover, the locking protrusion is released from the locking groove, so that the battery cover can rotate relative to the thermometer body. The positioning protrusion plays a blocking and limiting role on the sliding path of the shaft. At the same time, it cooperates with the locking protrusion and the locking groove to form a complex limiting and unlocking mechanism. When the positioning protrusion clamps the shaft with the groove wall, the locking protrusion engages with the groove to restrict rotation; after the shaft passes the positioning protrusion, the locking protrusion disengages from the groove, allowing rotation. This achieves precise control over the sliding and rotation of the battery cover, effectively restricting its movement when the battery cover needs to be fixed in position, and allowing it to be unlocked smoothly when the battery cover needs to be rotated. This meets the needs of battery cover operation in different usage scenarios and improves the flexibility and convenience of use.

[0012] Preferably, the positioning protrusion is an arc-shaped protrusion made of elastic material. The arc-shaped protrusion extends towards the battery cover that is not rotating relative to the thermometer body. The elastic material gives the positioning protrusion a certain degree of flexibility and elastic deformation capability. The design of the arc-shaped protrusion and the specific extension direction allow it to better adapt to the movement of the shaft when in contact with it, while providing appropriate resistance. During the sliding process of the shaft, the elastic arc-shaped positioning protrusion can effectively limit the movement without being too stiff, which would cause poor sliding or damage to the components. This improves the stability of the limiting and the smoothness of operation, and extends the service life of the components.

[0013] Preferably, the battery cover is provided with anti-slip grooves. The anti-slip grooves are used to increase the friction between the battery cover and the user's skin. By changing the texture and shape of the battery cover surface, the anti-slip grooves increase the coefficient of friction when in contact with the user's skin. When the user operates the battery cover, the anti-slip grooves can provide better grip and reduce the occurrence of operation errors caused by hand slippage, making the opening and closing operation of the battery cover more stable and accurate, and improving the user experience.

[0014] Preferably, a battery connecting piece is provided on the side of the battery cover away from the anti-slip groove. Two external batteries are provided in the battery compartment. The battery connecting piece is made of conductive material and is used to electrically connect the two external batteries in the battery compartment. The battery connecting piece acts as a conductive medium to connect the two external batteries in the battery compartment to form a complete circuit path, ensuring that the battery can supply power to the thermometer normally, so that the various functions of the thermometer can operate normally, and ensuring the measurement accuracy and stability of the thermometer.

[0015] Preferably, the battery connector is used to connect the two ends of two external batteries as the positive and negative connectors, respectively. This clearly distinguishes between the positive and negative connectors, accurately connecting the positive and negative terminals of the two batteries to establish the correct circuit polarity. This avoids circuit failures or damage to the thermometer caused by incorrect battery polarity connection, ensuring the stability and safety of battery power supply, ensuring the thermometer can work continuously and normally, and avoiding circuit interference.

[0016] The beneficial effects of this utility model are:

[0017] Effective anti-loss: The first slot effectively limits the battery cover, preventing it from detaching from the thermometer body. This prevents the battery cover from being lost, thus avoiding exposure of the battery compartment and ensuring safe battery use and normal operation of the thermometer. It also improves the convenience and user experience of using the thermometer.

[0018] Easy to operate: Simply push the button to open the battery cover, and it will automatically reset and close after being released. There is no need to disassemble or install the battery cover, simplifying the operation steps. It is especially suitable for quick operation in the elderly, children or medical scenarios.

[0019] Stable and reliable structure: smooth sliding fit and durable, not easily damaged after long-term use.

[0020] Easy to mass-produce: The overall structure can be achieved through injection molding, without the need for complex processing steps. It is highly compatible with existing thermometer production processes, has low production costs, and is suitable for large-scale industrial production. Attached Figure Description

[0030] Reference Figures 1 to 5 An infrared thermometer with a battery cover to prevent loss includes a thermometer body 1, a battery compartment 2 and a battery cover 3 for use with the battery compartment 2. The battery cover 3 is used to seal / protect the battery compartment 2 in conjunction with the thermometer body 1. A first groove 4 is formed on the thermometer body 1, and the battery cover 3 is partially housed in the first groove 4. The first groove 4 is used for the battery cover 3 to rotate and / or slide relative to the thermometer body 1, and the first groove 4 is used to prevent the battery cover 3 from detaching from the thermometer body 1.

[0031] Through the above structural design, in use, on the one hand, it provides the battery cover 3 with a rotating and / or sliding operating space relative to the thermometer body 1, allowing the battery cover 3 to open and close flexibly, facilitating the user's battery installation and removal operations; on the other hand, the first groove 4 effectively limits the battery cover 3, preventing it from detaching from the thermometer body 1, thereby achieving the technical effect of preventing the battery cover 3 from being lost, avoiding the exposure of the battery compartment 2 due to the loss of the battery cover 3, ensuring the safe use of the battery and the normal operation of the thermometer, while also improving the convenience and experience of the user in using the thermometer.

[0032] Specifically, the battery compartment 2 is equipped with reinforcing ribs and is integrally injection molded.

[0033] Specifically, the battery cover 3 is provided with a shaft 31. The battery cover 3 is rotated and / or slidably disposed in the groove via the shaft 31. The shaft 31 enables the battery cover 3 to rotate and / or slide flexibly around the shaft 31, thereby achieving efficient opening and closing of the battery cover 3 and improving the convenience of operation.

[0034] Specifically, there are two strip-shaped first grooves 4. The length direction of the first grooves 4 intersects the length direction of the shaft 31. The two first grooves 4 are located at both ends of the shaft 31 along its length direction, which are used to limit the sliding stroke of the battery cover 3. The first grooves 4 do not penetrate the thermometer body 1 along their length direction so that the battery cover 3 does not detach from the thermometer body 1. The two strip-shaped first grooves 4 that intersect the length direction of the shaft 31 provide a specific path for the sliding of the shaft 31. At the same time, through their non-penetrating design and the positions of the two ends, the sliding range of the shaft 31 is precisely limited, effectively controlling the sliding stroke of the battery cover 3, preventing the battery cover 3 from sliding excessively and detaching from the thermometer body 1, ensuring that the battery cover 3 always remains connected to the thermometer body 1, and ensuring the sealing of the battery compartment 2 and the safety of the battery.

[0035] Specifically, the thermometer body 1 and the battery cover 3 are respectively provided with a first limiting member 5 and a second limiting member 32. When the battery cover 3 is in a preset position and does not slide relative to the thermometer body 1, the second limiting member 32 is engaged with the first limiting member 5 so that the battery cover 3 cannot rotate relative to the thermometer body 1. The first limiting member 5 and the second limiting member 32 cooperate with each other to form an engaging structure when the battery cover 3 is in a specific preset position and does not slide, preventing the battery cover 3 from rotating. When the battery cover 3 does not need to rotate, it can stabilize the position of the battery cover 3, avoid the battery cover 3 from becoming loose or the battery compartment 2 from being exposed due to accidental rotation, ensure the stable and closed state of the battery compartment 2, and improve the safety of the thermometer.

[0036] Specifically, the second limiting member 32 is located on the battery cover 3 at the end away from the shaft 31, and the first limiting member 5 is located on the thermometer body at the end away from the first groove 4 to work in conjunction with the second limiting member 32. The second limiting member 32 and the first limiting member 5 are respectively located on the battery cover 3 and the thermometer body 1 at positions relatively away from the shaft 31 and the first groove 4, so that the two can accurately correspond and engage at specific positions. This optimizes the design layout of the limiting structure, improves the accuracy and reliability of the limiting, and ensures that the first limiting member 5 and the second limiting member 32 can effectively cooperate when limiting is required, thereby enhancing the restriction effect on the rotation of the battery cover 3.

[0037] Specifically, the thermometer body 1 is provided with a positioning protrusion 6 located in the first groove 4. The positioning protrusion 6 is located on the sliding path of the shaft 31. The positioning protrusion 6 is used to limit the sliding of the battery cover 3 relative to the thermometer body 1. The second limiting member 32 is a locking protrusion, and the first limiting member 5 is a locking groove. When the positioning protrusion 6 clamps and limits the shaft 31 with one end of the groove wall of the first groove 4, the locking protrusion is locked in the locking groove to prevent the battery cover 3 from rotating relative to the thermometer body 1. After the shaft 31 passes the positioning protrusion 6 by sliding the battery cover 3, the locking protrusion is released from the locking groove, so that the battery cover 3 can rotate relative to the thermometer body 1. The positioning protrusion 6 plays a blocking and limiting role on the sliding path of the shaft 31. At the same time, it cooperates with the locking protrusion and the locking groove to form a complex limiting and unlocking mechanism. When the positioning protrusion 6 clamps the shaft 31 with the groove wall, the locking protrusion engages with the groove to restrict rotation; after the shaft 31 passes the positioning protrusion 6, the locking protrusion disengages from the groove, allowing rotation. This achieves precise control over the sliding and rotation of the battery cover 3. When it is necessary to fix the position of the battery cover 3, its movement can be effectively restricted. When it is necessary to rotate the battery cover 3, it can be unlocked smoothly, meeting the needs of operating the battery cover 3 in different usage scenarios and improving the flexibility and convenience of use.

[0038] Specifically, the positioning protrusion 6 is an arc-shaped protrusion made of elastic material. The arc-shaped protrusion extends towards the battery cover 3, which is not rotated relative to the thermometer body 1. The elastic material gives the positioning protrusion 6 a certain degree of flexibility and elastic deformation capability. The arc-shaped protrusion design and specific extension direction allow it to better adapt to the movement of the shaft 31 when in contact with it, while providing appropriate resistance. During the sliding process of the shaft 31, the elastic arc-shaped positioning protrusion 6 can effectively limit the movement without being too stiff, which would cause poor sliding or damage to the parts. This improves the stability of the limiting and the smoothness of operation, and extends the service life of the parts.

[0039] Specifically, the battery cover 3 is provided with anti-slip grooves 33. The anti-slip grooves 33 are used to increase the friction between the battery cover 3 and the user's skin. By changing the texture and shape of the surface of the battery cover 3, the anti-slip grooves 33 increase the coefficient of friction when in contact with the user's skin. When the user operates the battery cover 3, the anti-slip grooves 33 can provide better grip and reduce the operation error caused by hand slippage, making the opening and closing operation of the battery cover 3 more stable and accurate, and improving the user experience.

[0040] Specifically, a battery connecting piece 7 is provided on the side of the battery cover 3 away from the anti-slip groove 33. Two external batteries are provided in the battery compartment 2. The battery connecting piece 7 is made of conductive material and is used to electrically connect the two external batteries in the battery compartment 2. As a conductive medium, the battery connecting piece 7 connects the two external batteries in the battery compartment 2 to form a complete circuit path, ensuring that the battery can supply power to the thermometer normally, so that the various functions of the thermometer can operate normally, and ensuring the measurement accuracy and stability of the thermometer.

[0041] Specifically, the battery connector 7 is used to connect the two ends of two external batteries as the positive and negative connectors, respectively. This clearly distinguishes between the positive and negative connectors, accurately connecting the positive and negative terminals of the two batteries to establish the correct circuit polarity. This avoids circuit failures or damage to the thermometer caused by incorrect battery polarity connection, ensuring the stability and safety of battery power supply, ensuring the thermometer can work continuously and normally, and preventing circuit interference.

[0042] Specifically, the closed contact surface between the battery cover 3 and the thermometer body 1 is equipped with a magnetic attraction component, which consists of a permanent magnet with opposite magnetic poles and a magnetic conductive sheet. The permanent magnet is embedded in the thermometer body 1, and the magnetic conductive sheet is fixed to the corresponding position on the battery cover 3.

[0043] Component manufacturing

[0044] The thermometer body 1 is injection molded from ABS engineering plastic. The first groove 4 is machined on both sides of the battery compartment at the rear of the body (the first groove 4 has a longitudinal guide section length of 25mm and a transverse limiting section length of 8mm).

[0045] The battery cover is also made of ABS plastic injection molding.

[0046] The push button is made of ABS plastic, with a one-piece molded connecting post at the bottom (3mm in diameter). The compression spring is made of stainless steel (0.5mm in wire diameter, 15mm in free length).

[0047] An elastic element may be provided between the shaft 31 and the battery cover 3 for easy installation.

[0048] Specifically, the usage process of this battery cover-protected infrared thermometer is as follows:

[0049] Closed state: The battery cover 3 is completely attached to the thermometer body 1. The elastic limiting protrusion (first limiting member 5) on the thermometer body 1 is engaged in the positioning groove (second limiting member 32) on the edge of the battery cover 3. At this time, the battery cover 3 is locked and cannot slide freely. The battery compartment 2 is in a sealed protection state to prevent dust or liquid from entering.

[0050] Opening process:

[0051] Operating anti-slip groove 33: When the user's fingers touch the anti-slip groove 33 on the surface of the battery cover 3, the friction is increased to stabilize the grip;

[0052] Push button to unlock: Push the push button set at the tail of the thermometer body 1 with your finger, and drive the battery cover 3 to slide along the longitudinal guide section (25mm in length) of the first groove 4, and the shaft 31 moves in the strip-shaped first groove 4;

[0053] Fully open: Push the shaft 31 past the positioning protrusion 6, the locking protrusion (second limiting member 32) disengages from the locking groove (first limiting member 5), the battery cover 3 can rotate, and the battery compartment 2 is fully exposed. At this time, because the first groove 4 does not penetrate the thermometer body 1, the battery cover 3 will not detach from the body.

[0054] Battery replacement: The battery compartment 2 contains two external batteries, which are electrically connected through the battery connector 7 (positive connector / negative connector) to ensure correct circuit polarity and avoid malfunctions.

[0055] Closing process: After replacing the battery, rotate the battery cover 3 in the reverse direction. The battery cover 3 slides back to its original position along the first groove 4. When the shaft 31 slides back to the position of the positioning protrusion 6, the elastic limiting protrusion (first limiting member 5) is engaged in the positioning groove (second limiting member 32), and the battery cover 3 is locked again, restoring the closed state.
