Description

Technical Field

[0001] The utility model relates to the technical field of body temperature testing, in particular to an electronic thermometer that is safe to use. Background Art

[0002] Most existing electronic thermometers are composed of the following structures: a shell, one end of which is connected to a temperature sensing head, and the other end of which is open and has an opening. A core module for measuring temperature can be installed in the shell through the opening. The core module includes a plastic bearing seat and a temperature measuring circuit board and a display screen arranged on the front and back sides of the bearing seat; a battery mounting portion is formed at the end of the bearing seat located at the opening of the shell, and a button battery is installed in the battery mounting portion through a prefabricated groove; Figure 6 As shown, when the movement module is assembled with the shell, most of the movement module is located inside the shell, with only the display screen exposed at the window position in the middle of the shell and the battery mounting part loaded with button batteries exposed at the opening position. This is to facilitate battery replacement, and secondly, in case of movement failure, the movement module can be pulled out by pinching this part for repair.

[0003] During normal daily use, the open end of the shell is connected to the cap body by plugging and unplugging. The cap body can close the opening of the shell and seal the button battery near the shell opening. When the battery needs to be replaced, the user can pull off the cap body to expose the battery installation part, pinch this part to pull out the temperature measurement module and then replace the battery.

[0004] Specifically, after removing the cap of the thermometer, you can see part of the circuit board and the button battery mounted on the end of the mounting base, such as Figure 6 As shown, although the groove notch of the battery mounting portion at the end of the support seat is provided with a buckle to prevent the button battery from falling off, in order to facilitate repair and replacement of the battery, most of the button battery is exposed and the battery is small. If a younger child takes the thermometer and plays with it as a toy, the cap can still be pulled off to easily pull out the button battery, which can easily cause a safety accident of accidentally swallowing the battery. Summary of the invention

[0005] In order to solve the above-mentioned technical problems, the purpose of the utility model is to provide an electronic thermometer that is safe to use. A protective cover is fixed above the battery mounting portion of the support base by screws. The protective cover can cover the button battery and prevent the battery from falling off, thereby reducing the possibility of children lifting the protective cover and contacting the button battery, thereby further improving safety.

[0006] The technical solution of the utility model is achieved in this way:

[0007] A safe electronic thermometer comprises: a shell with an opening at one end, a temperature measuring movement module installed inside the shell, a cap body for sealing the opening connected to the rear opening of the shell, the movement module comprising a bearing seat and a circuit board connected to the bearing seat, a battery mounting portion is formed at one end of the bearing seat close to the shell opening, a button battery is placed in the mounting groove of the battery mounting portion, after the bearing seat is placed in the shell, the battery mounting portion is exposed outside the shell opening, a protective cover for covering the button battery is connected to the battery mounting portion, and the protective cover is directly or indirectly connected and fixed to the bearing seat by screws.

[0008] Preferably, a plurality of buckles for limiting the detachment of the button battery are extended upwards on both sides of the notch of the battery mounting portion, and a avoidance groove is provided at the corresponding position of the protective cover facing the battery mounting portion. When the protective cover is installed in place, the buckles are in the corresponding avoidance grooves. The prefabricated buckles of the battery mounting portion limit the button battery in the battery mounting portion, so that the battery will not fall off accidentally, and at the same time, a restriction is added to the protective cover to prevent it from falling off.

[0009] Preferably, the protective cover is directly connected and fixed to the bearing seat by screws, which means that: a threaded hole is provided on the bearing seat, and the protective cover is connected and fixed to the bearing seat by screws.

[0010] Preferably, the protective cover is indirectly connected and fixed to the bearing seat by screws, which means that a threaded hole is opened on the circuit board, the circuit board is restricted by the shell so that it remains relatively fixed with the bearing seat in the thickness direction of the shell, and the protective cover is connected and fixed to the circuit board by screws. Since the electronic thermometer has a relatively compact structure, if the screws cannot be directly installed on the bearing seat, connecting the protective cover and the circuit board by screws, that is, indirectly connecting the protective cover and the bearing seat, can avoid increasing the volume of the electronic thermometer.

[0011] Preferably, the protective cover comprises a plate-shaped body for covering the mounting slot and a connecting portion extending from the plate-shaped body toward the housing, the connecting portion is provided with a through hole for screws to pass through, and after the connecting portion rests on the exposed portion of the circuit board, the through hole is aligned with the threaded hole. The plate-shaped body of the protective cover is used to cover the button battery, and the through hole provided on the connecting portion is used to achieve screw connection.

[0012] Preferably, an annular contraction part is provided at the rear of the shell for plugging with the cap body. Since the electronic thermometer has a compact structure, in order to facilitate battery replacement without increasing the volume of the electronic thermometer, a notch is provided on the annular contraction part, and the connecting part is located in the notch. After the screw is installed, the screw cap is not higher than the outer surface of the annular contraction part. Through the notch of the annular contraction part of the shell, the user can directly unscrew the screw when repairing or replacing the battery without taking out the entire movement module, avoiding interference between the shell and the screwdriver, and facilitating battery replacement or repair.

[0013] Preferably, a plurality of positioning teeth extend from the connecting portion toward the closed end of the housing. Positioning posts are provided on the circuit board near the notch of the annular contraction portion. After the positioning teeth are installed, the positioning posts are located between two adjacent positioning teeth. Neither the positioning teeth nor the positioning posts are higher than the outer surface of the annular contraction portion, and both the positioning posts and the positioning teeth are hidden inside the housing. The design of the positioning teeth and the positioning posts further limits the position of the protective cover and prevents the protective cover from shifting.

[0014] Preferably, an arc-shaped rib or spaced convex teeth extend downward from the edge of the plate-shaped body. When the protective cover is installed in place, the arc-shaped rib or convex teeth surround the periphery of the notch of the installation groove and form an up-and-down stagger with the installation groove. Since only the connecting portion of the protective cover is connected to the circuit board by screws to prevent the protective cover from falling off, and there is no anti-detachment connection at the end opposite to the connecting portion, it is very likely that a child will lift the protective cover from the other end. The edge structure of the plate-shaped body of the protective cover avoids this possibility. The up-and-down stagger structure formed by the arc-shaped rib or convex teeth and the installation groove makes there no obvious gap at this connection, and it is difficult to apply force.

[0015] The principle and beneficial effects of the present utility model adopting the above technical solutions are as follows:

[0016] 1. The present utility model provides a safe-to-use electronic thermometer. By adding a protective cover element and directly or indirectly connecting the plastic protective cover to the carrier seat, the button battery is fixed and constrained and mostly covered, greatly reducing the possibility of a child accidentally swallowing the battery.

[0017] 2. By directly or indirectly connecting the connecting portion of the protective cover and the carrier seat with screws, a screwdriver is a commonly used repair and installation tool in a family, generally stored in a toolbox and not placed within reach of children. For adults, the screwdriver is relatively easy to obtain, while for children, it is difficult to obtain both the electronic thermometer and the screwdriver at the same time; even if a child gets the screwdriver, it is very difficult for the child to use the screwdriver to unscrew the screw because the screw is small and delicate. Therefore, using screw connection reduces the risk of a child contacting and swallowing the button battery.

[0018] 3. The arc-shaped rib or spaced convex teeth extending downward from the edge of the plate-shaped body of the protective cover will surround the periphery of the notch of the installation groove and form an up-and-down stagger with the installation groove when installed in place. When the protective cover is installed, there is no obvious gap at the connection between the protective cover and the carrier seat, and it is difficult for a child to lift the protective cover easily, which reduces the risk of a child accidentally swallowing the button battery after contacting it.

Detailed implementation manners

[0026] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention will be further described in detail below with reference to the drawings and specific implementation manners. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0027] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited by the specific embodiments disclosed below.

[0028] The specific implementation manners of the present invention are as follows:

[0029] Please refer to Figures 1 - 5The present embodiment proposes a safe electronic thermometer, comprising an integrally formed shell 2, one end of which is connected to a temperature sensing probe, and the other end is an open opening, the opening being connected to a cap body 1 for sealing the opening, a through slot being opened in the middle of the shell 2, a temperature measuring movement module being installed inside the shell 2, the movement module comprising a display screen for displaying the measured temperature, a support seat 6, and a circuit board 5 connected to the support seat 6, the support seat 6 being installed and connected with a display screen, the size of the display screen being consistent with the through slot opened in the shell, and when the movement module is installed in the shell, the display screen can be completely exposed in the through slot opened in the shell; a battery mounting portion 601 is formed at one end of the support seat 6 close to the opening of the shell 2, a button battery 7 is placed in the mounting slot 603 of the battery mounting portion 601, after the support seat 6 is placed in the shell 2, the battery mounting portion 601 is exposed outside the opening of the shell 2, the focus of the present embodiment is that a protective cover 3 for covering the button battery 7 is connected to the battery mounting portion 601, and the protective cover 3 is directly or indirectly connected and fixed to the support seat 6 by screws 4.

[0030] The above introduces the general composition of the electronic thermometer. Next, we will give a detailed introduction to each part:

[0031] Specifically, if Figure 1 or Figure 3 As shown, in order not to affect the installation of the protective cover 3 and to make the installation of the protective cover 3 more comfortable, a corresponding position of the protective cover 3 facing the battery installation part 601 is provided with an escape groove 302. When the protective cover 3 is installed in place, the undercut 602 is in the corresponding escape groove 302. The undercut 602 prefabricated on the battery installation part 601 restricts the button battery 7 in the battery installation part 601, so that the battery will not fall off accidentally, and at the same time, it also adds a restriction to the protective cover to prevent it from falling off.

[0032] Furthermore, in order to fix the protective cover 3, the protective cover 3 is directly or indirectly connected and fixed to the bearing seat 6 by screws 4, and the protective cover 3 can be fixed by direct or indirect connection. The protective cover 3 is directly connected and fixed to the bearing seat 6 by screws 4, which means: a threaded hole is provided on the bearing seat 6, and the protective cover 3 is connected and fixed to the bearing seat 6 by screws 4; the protective cover 3 is indirectly connected and fixed to the bearing seat 6 by screws 4, which means: a threaded hole is provided on the circuit board 5, and the circuit board 5 is restricted by the shell 2 so that it is relatively fixed with the bearing seat 6 in the thickness direction of the shell 2, and the protective cover 3 is connected and fixed to the circuit board 5 by screws 4, and holes are provided at the corresponding connection points of the circuit board 5 or the bearing seat 6, so that the connection and fixation between the protective cover 3 and the bearing seat 6 is realized by screws 4. For ordinary users, the screw 4 connection is not only convenient for installation and disassembly, but also low in cost; and it is difficult for children to unscrew the screws 4 without a screwdriver, which reduces the risk of children swallowing button batteries 7 after contact.

[0033] As Figure 3 shown, in this embodiment, the screw 4 is installed in the following manner: the screw 4 passes through the through hole 301 provided in the protective cover 3 and is screwed into the threaded hole provided in the circuit board 5, while the protective cover 3 restricts and covers the button battery 7 at the same time.

[0034] More specifically, the covering of the button battery 7 by the protective cover 3 and the connection between the protective cover 3 and the carrier seat 6 are realized as follows: the protective cover 3 includes a plate-shaped body 303 for covering the mounting groove 603 and a connecting portion 304 extending from the plate-shaped body 303 towards the housing 2. A through hole 301 for the screw 4 to pass through is provided on the connecting portion 304. After the connecting portion 304 abuts against the exposed part of the circuit board 5, the through hole 301 is aligned with the threaded hole. The plate-shaped body 303 of the protective cover 3 is used to cover the button battery 7, and the through hole 301 provided on the connecting portion 304 is used to realize the connection of the screw 4.

[0035] Furthermore, a ring-shaped constriction 201 for plugging and mating with the cap body 1 is provided at the tail of the housing 2. Since the electronic thermometer has a compact structure, in order to facilitate battery replacement without increasing the volume of the electronic thermometer, a notch is provided on the ring-shaped constriction 201. The connecting portion 304 is located within the notch. After the screw 4 is installed, the head of the screw 4 does not protrude above the outer surface of the ring-shaped constriction 201; through the notch of the ring-shaped constriction 201 of the housing 2, the user can directly unscrew the screw 4 when repairing or replacing the battery, without having to take out the entire movement module, avoiding interference between the housing 2 and the screwdriver for the screw 4, and facilitating battery replacement or repair.

[0036] Furthermore, as Figure 3 shown, the connecting portion 304 extends towards the closed end of the housing with a plurality of positioning teeth 305. A positioning post 502 is provided on the circuit board 5 near the notch of the ring-shaped constriction 201. After the positioning teeth 305 are installed, the positioning post 502 is located between two adjacent positioning teeth 305. Neither the positioning teeth 305 nor the positioning post 502 protrude above the outer surface of the ring-shaped constriction 201, and both the positioning post and the positioning teeth are hidden inside the housing; the design of the positioning teeth and the positioning post 502 further restricts the position of the protective cover 3 and prevents the protective cover 3 from shifting.

[0037] Even further, since only the connecting portion 304 of the protective cover 3 is connected to the circuit board 5 by the screw 4 to prevent the protective cover 3 from falling off, and there is no anti-detachment connection at the end opposite to the connecting portion 304, it is very likely that a child will lift the protective cover 3 from the other end. In order to prevent a child from lifting the protective cover 3 from the end opposite to the connecting portion 304, an arc-shaped edge 307 or spaced convex teeth 306 extend downward from the edge of the plate-shaped body 303 of the protective cover 3. The specific connection method is as follows: as Figure 3 and Figure 4As shown in the figure, when the edge of the plate-shaped body 303 of the protective cover 3 extends downward with spaced convex teeth 306, a groove 604 matching the convex teeth 306 is provided at the notch of the battery installation groove 603. After the protective cover 3 is installed in place, the convex teeth 306 surround the periphery of the notch of the installation groove 603 and form an up-and-down stagger with the installation groove 603, and there is no obvious gap at the connection between the convex teeth 306 and the groove 604; as another implementation method, the edge of the plate-shaped body 303 of the protective cover 3 extends downward with an arc-shaped edge 307, and the arc-shaped edge 307 cooperates with the notch of the battery installation groove 603, and there is no obvious gap in the middle. After the protective cover is installed in place, the arc-shaped edge 307 of the protective cover and the notch of the battery installation groove 603 form a naturally transitioning arc surface. Therefore, when a child wants to use a finger to lift the protective cover 3 from the connection between the arc-shaped edge 307 and the notch of the installation groove, since it is difficult to apply force at this arc surface, the child's finger will slide to the plane of the plate-shaped body 303 of the protective cover; through these two connection methods, the tightening and fixing effect on the protective cover 3 can be achieved. Then, when a child plays with this electronic thermometer as a toy and pulls off the cap body 1, only the protective cover 3 covering the button battery 7 and a small part of the battery installation part 601 can be seen, and the protective cover 3 cannot be lifted by fingering, and thus the battery cannot be directly contacted, reducing the possibility of a child accidentally swallowing the battery and improving the safety of the electronic thermometer.

[0038] Furthermore, the screw connection between the protective cover 3 and other modules of the movement will not cause more inconvenience to the normal battery replacement or repair. When a normal user needs to replace the battery, just pull off the cap body 1, use a screwdriver to unscrew the screw 4, take off the protective cover 3, then the button battery can be seen. Then take off the button battery 7 to be replaced, put a new button battery 7 in the installation groove 603, place the protective cover 3, and then screw the screw 4 tightly, and the battery replacement is completed.

[0039] The above has schematically described the present invention and its implementation manners. This description is not restrictive, and what is shown in the drawings is only one of the implementation manners of the present invention, and the actual structure is not limited thereto. Therefore, if those of ordinary skill in the art are inspired by it and, without departing from the gist of the creation of the present invention, design structurally similar ways and embodiments to this technical solution without creative efforts, they shall fall within the protection scope of the present invention.
