Technical Field
[0001] This utility model relates to the field of ear thermometer technology, specifically to an ear thermometer with an automatically pop-out battery cover. Background Technology
[0002] An ear thermometer is a device used to measure body temperature. It uses an infrared sensor to detect infrared radiation emitted by the eardrum inside the ear canal, converts it into an electrical signal, and then uses an internal chip to calculate the accurate body temperature.
[0003] An ear thermometer mainly consists of a housing, battery, battery cover, and probe. As the battery is used for a long time, its charge will decrease. Therefore, for continued use, the operator will often remove the battery cover to replace the battery.
[0004] In terms of the way the battery cover is removed, there are two main types: the first is the push-pull battery cover; the second is the snap-on battery cover.
[0005] In practice, the above two types of battery covers have the following problems:
[0006] Firstly, push-pull battery covers are convenient to use, and most household appliances use this design (such as air conditioner remote controls). Specifically, when using this design, you can push the battery cover with one hand until it engages with the latch on the device housing. However, if you push and pull too many times during this process, the engagement point between the battery cover and the device housing will rub repeatedly, reducing the locking force and making the battery cover risk falling off. In other words, the push-pull battery cover may not lock securely during use.
[0007] Secondly, for snap-on battery covers, both ends have protrusions, and the device housing has corresponding slots. When using them, the protrusions need to be inserted into the corresponding slots. If operated with one hand, the protrusions may get stuck during insertion. Therefore, most users choose to operate with both hands to ensure that both ends of the snap-on battery cover can be quickly and accurately inserted into the device housing. In other words, because both ends of the snap-on battery cover have protrusions, there is a possibility that the protrusions may get stuck in the slots, making it somewhat difficult to install and remove the snap-on battery cover.
[0008] Therefore, how to overcome the shortcomings of the existing technology mentioned above has become the subject of this utility model. Utility Model Content
[0009] This invention provides an ear thermometer with an automatically pop-out battery cover, aiming to solve the technical problems mentioned in the background art.
[0010] To achieve the above objectives, the technical solution adopted by this utility model is: an ear thermometer with an automatically pop-out battery cover, comprising a housing, a battery cover, and a dial module;
[0011] The housing has a battery compartment slot, and the battery cover is positioned and connected to the opening of the battery compartment slot to close the battery compartment slot; the toggle module is disposed on the housing and located beside the battery compartment slot.
[0012] The toggle module includes a sliding block, which is slidably connected to the housing.
[0013] The end of the sliding block near the battery compartment is the working end. The working end is provided with an ejection part and a locking part. The ejection part and the locking part are arranged separately in the sliding direction of the sliding block. There is a locking insertion space between the ejection part and the locking part.
[0014] The battery cover has a latch on the surface facing the battery compartment slot. When the battery cover is positioned and connected to the slot of the battery compartment slot, the latch is configured to act within the locking insertion space.
[0015] Along the sliding direction of the sliding block, at the end of the latch away from the battery cover, a hook platform is provided on one side edge and an ejection slope is provided on the other side edge, the ejection slope being inclined away from the hook platform.
[0016] The hook platform is provided correspondingly to the locking part, and the ejection ramp is provided correspondingly to the ejection part;
[0017] The sliding block has a locked state and an ejected state;
[0018] In the locked state, the ejector part abuts against the ejector ramp, and the locking part hooks the hook platform part to fix the battery cover relative to the housing.
[0019] In the ejected state, the locking part is just disengaged from the hook platform part, and the ejecting part pushes the latch away from the housing by sliding along the ejection ramp.
[0020] In the above scheme, the specific setting position of the sliding block is not fixed. Since the sliding block and the latch cooperate with each other, (assuming that the battery compartment is a quadrilateral structure) when the sliding block is set at the edge of the battery compartment along the length direction, the latch is also set at the edge of the battery cover along the length direction.
[0021] In the above scheme, the width of the insertion space should not be less than the thickness of the latch, only in this way can the latch be properly inserted into the insertion space.
[0022] In the above scheme, the ejector part can be a slope, point, or edge that contacts the ejector ramp. However, the setting of a point or edge indicates that the pushing force on the ejector ramp is in a small area, which makes the thrust on the latch unbalanced.
[0023] A further technical solution is that the angle between the ejector inclined surface and the sliding direction of the sliding block is less than 45 degrees. This angle can be referenced... Figure 9 As shown, it is referred to by α. If α is greater than 45 degrees (for example, 90 degrees is directly selected), when the ejector part contacts the ejector ramp, the force applied by the ejector part on the ejector ramp is perpendicular to the latch, so the latch cannot be pushed out. If it is between 90 degrees and 45 degrees, most of the force is perpendicular to the latch, and a small part is parallel to the latch, making it more difficult to push the latch out. Therefore, this design ensures that when the ejector ramp contacts the sliding block, most of the force is parallel to the latch, and only a small part of the force is perpendicular to the latch.
[0024] In a further technical solution, the ejector portion is a pushing inclined surface that slides in conjunction with the ejector inclined surface, and the angle of the pushing inclined surface is the same as that of the ejector inclined surface.
[0025] This design makes the thrust applied to the ejector ramp by the ejector part more stable.
[0026] In a further technical solution, the housing has an installation chamber located inside, the installation chamber being positioned at the edge of the battery compartment, and the sliding block being positioned within the installation chamber.
[0027] This design allows the sliding block to be installed inside the mounting chamber, reducing the likelihood of wobbling during subsequent sliding.
[0028] In a further technical solution, an elastic element is provided on the side of the sliding block. One end of the elastic element acts on the inner side wall of the installation chamber, and the other end acts on the side of the sliding block, so that the locking part maintains the tendency to slide towards the hook platform.
[0029] This design makes the slider more stable in both locked and ejected states, preventing it from becoming loose.
[0030] In a further technical solution, the sliding block has a limiting groove on its side to limit the end of the elastic member, and a top rod coaxially arranged with the elastic member is provided in the limiting groove.
[0031] The presence of the push rod and the limiting groove can provide axial limiting when the elastic element is compressed, ensuring that the direction of the elastic force applied by the elastic element is always parallel to the sliding direction.
[0032] In a further technical solution, the surface of the housing also has a sliding guide groove, which is correspondingly arranged with the mounting chamber, and the sliding guide groove is a long strip structure; the surface of the sliding block is provided with a sliding knob that is positioned and connected in the sliding guide groove.
[0033] The sliding guide groove is designed to control the sliding distance of the slider.
[0034] In a further technical solution, the length of the locking insertion space is less than the maximum sliding stroke of the sliding knob along the sliding guide groove.
[0035] If the size is too large, it is easy for the sliding knob to slide from one end to the other in the sliding guide groove, but the ejector part still does not eject the latch, meaning the battery cover cannot automatically pop out.
[0036] A further technical solution is provided in the inner wall of the installation chamber, the guide strip is arranged parallel to the sliding direction of the sliding block, and the surface of the sliding block is provided with a guide groove that cooperates with the guide strip.
[0037] By combining the guide bar and the guide groove, not only can the stability of the slider be improved during sliding, but the maximum sliding stroke of the slider can also be further limited.
[0038] In a further technical solution, the mounting chamber has a socket, which is configured to guide the latch into the locking insertion space when the battery cover is positioned and connected to the slot of the battery compartment.
[0039] The above design ensures that the latch and the locking insertion space will not easily malfunction during matching.
[0040] A further technical solution involves providing a probe module at the end of the housing; the outer periphery of the housing serves as a gripping part when using the probe module.

[0042] The terms "connection" or "positioning" as used in this article can refer to two or more components or devices making direct physical contact with each other, or making indirect physical contact with each other, or to two or more components or devices operating or moving with each other.

[0046] The working principle and advantages of this utility model are as follows:
[0047] This invention enables the battery cover to be quickly locked and automatically pop open after locking through the cooperation of the toggle module and the latch, unlike push-pull battery covers which are difficult to lock. In this invention, when the battery cover is positioned and connected to the slot of the battery compartment, the latch is configured to act in the locking insertion space. At this time, the locking part will hook the hook platform part to lock the battery cover. The locking operation is easy and the locking is very secure.
[0048] Secondly, unlike snap-on battery covers which have protrusions at both ends, making it difficult to disassemble or assemble the battery cover due to the protrusions getting stuck in the slots, this utility model allows the sliding block to be moved to disengage the locking part from the hook platform. Then, the ejector part slides along the ejector ramp to push the latch away from the housing, making it easier to eject. Attached Figure Description

[0062] The present invention will be further described below with reference to the accompanying drawings and embodiments:
[0063] Example: The present invention will be clearly described below with illustrations and detailed description. Any person skilled in the art who understands the examples of the present invention can make changes and modifications based on the technology taught in the present invention without departing from the spirit and scope of the present invention.
[0064] The terminology used herein is for the purpose of describing specific embodiments only and is not intended to limit the scope of this work. Singular forms such as “a,” “this,” “this,” “the,” and “the” as used herein also include plural forms.
[0065] See appendix Figures 1-12 As shown, an ear thermometer with an automatically pop-out battery cover includes a housing 1, a battery cover 3, and a toggle module 10.
[0066] The housing 1 has a battery compartment 4, and the battery cover 3 is positioned and connected to the opening of the battery compartment 4 to close the battery compartment 4; the toggle module 10 is disposed on the housing 1 and located on the side of the battery compartment 4.
[0067] The toggle module 10 includes a sliding block 11, which is slidably connected to the housing 1;
[0068] The end of the sliding block 11 near the battery compartment 4 is the working end. The working end is provided with an ejection part 15 and a locking part 14. The ejection part 15 and the locking part 14 are arranged separately in the sliding direction of the sliding block 11. There is a locking insertion space 16 between the ejection part 15 and the locking part 14.
[0069] The battery cover 3 has a latch 5 on the side facing the battery compartment 4. When the battery cover 3 is positioned and connected to the slot of the battery compartment 4, the latch 5 is configured to act within the locking insertion space 16.
[0070] Along the sliding direction of the sliding block 11, at the end of the latch 5 away from the battery cover 3, a hook platform 6 is provided on one side edge and an ejection slope 7 is provided on the other side edge. The ejection slope 7 is inclined away from the hook platform 6.
[0071] Among them, the hook platform 6 is correspondingly provided with the locking part 14, and the ejection inclined surface 7 is correspondingly provided with the ejection part 15;
[0072] Sliding block 11 has a locked state and an ejected state;
[0073] In the locked state, the ejector 15 abuts against the ejector ramp 7, and the locking part 14 hooks the hook platform 6 so that the battery cover 3 is fixed relative to the housing 1.
[0074] In the ejected state, the locking part 14 is just disengaged from the hook platform part 6, and the ejecting part 15 pushes the latch 5 away from the housing 1 by sliding along the ejection ramp 7.
[0075] In the above scheme, the ejector part 15 and the locking part 14 can have the following design schemes: 1. They can be as follows: Figure 8 As shown, the ejector part 15 and the locking part 14 are two independent structures (the two structures can be installed on the end face of the working end, or they can be recessed into the end face of the working end); 2. The ejector part 15 and the locking part 14 are integrally formed with the sliding block 11 and have the same thickness, with only a locking insertion space 16 and a pushing slope provided. In specific operation, the configuration is set according to the requirements, and the first type is selected in this application. This ensures that when the locking part 14 hooks the hook platform 6, the difficulty of hooking the hook platform 6 will not increase due to the thickness of the locking part 14.
[0076] This utility model enables the battery cover to be quickly locked and automatically pop open after locking through the cooperation of the toggle module 10 and the latch 5, which is different from the case of the push-pull battery cover which is not secure when in use. In this utility model, when the battery cover 3 is positioned and connected to the slot of the battery compartment 4, the latch 5 is configured to act in the locking insertion space 16. At this time, the locking part 14 will hook the hook platform part 6 to lock the battery cover 3. The locking operation is easy and the locking is secure.
[0077] Secondly, unlike snap-on battery covers which have protrusions at both ends, making it difficult to disassemble or assemble the battery cover due to the protrusions getting stuck in the slots, in this utility model, the sliding block 11 can be moved to disengage the locking part 14 from the hook platform part 6, and then the ejecting part 15 slides along the ejecting slope 7 to push the latch 5 away from the housing 1, making it easier to eject.
[0078] Reference Figure 9 The hook platform 6 is provided with an inlet ramp on the side away from the battery cover 3 and a hook plane on the side closer to the battery cover 3.
[0079] Specifically, during fixing, the battery cover 3 is directly guided to the slot of the battery compartment 4. Then, the latch 5 is configured to act within the locking insertion space 16. When the latch 5 enters the locking insertion space 16, the locking part 14 will first contact the guide slope on the hook platform 6. As the latch 5 continues to enter, the locking part 14 will slide along the guide slope. During this process, the sliding block 11 and the ejector part 15 will also slide. Afterward, the locking part 14 will slide to the hook plane.
[0080] At this time, the ejector part 15 abuts against the ejector ramp 7, and the locking part 14 hooks the hook platform part 6 so that the battery cover 3 is fixed relative to the housing 1.
[0081] Once the battery cover 3 needs to be released, simply push the sliding block 11 to slide it so that the locking part 14 just disengages from the hook platform part 6. Then continue to push the sliding block 11, and then the ejector part 15 pushes the latch 5 away from the housing 1 by sliding along the ejector ramp 7.
[0082] In some specific embodiments, the angle between the ejector ramp 7 and the sliding direction of the sliding block 11 is less than 45 degrees.
[0083] The included angle can be referenced here. Figure 9As shown, it is referred to as α. If α is greater than 45 degrees (for example, 90 degrees is directly selected), when the ejector part 15 contacts the ejector ramp 7, the force applied by the ejector part 15 to the ejector ramp 7 is perpendicular to the latch 5, so the latch 5 cannot be pushed out. If it is between 90 degrees and 45 degrees, most of the force is perpendicular to the latch 5, and a small part is parallel to the latch 5, making it more difficult to push the latch 5 out. Therefore, this design ensures that when the ejector ramp 7 contacts the sliding block 11, most of the force is parallel to the latch 5, and only a small part of the force is perpendicular to the latch 5.
[0084] In some specific embodiments, the ejector 15 is a pushing slope that slides with the ejector slope 7, and the angle of the pushing slope is the same as that of the ejector slope 7.
[0085] By making the pushing ramp parallel to the ejection ramp 7, the contact area between the ejection part and the ejection ramp 7 can be increased. Compared with the contact between a point and an edge, the thrust applied by the ejection part to the ejection ramp is more stable.
[0086] In some specific embodiments, the housing 1 has an installation chamber 8 inside, which is located at the edge of the battery compartment 4, and the sliding block 11 is located inside the installation chamber 8.
[0087] This design allows the sliding block 11 to be installed inside the mounting chamber 8, reducing the likelihood of shaking during subsequent sliding.
[0088] In some specific embodiments, an elastic element 13 is also provided on the side of the sliding block 11. One end of the elastic element 13 acts on the inner wall of the mounting chamber 8, and the other end acts on the side of the sliding block 11, so that the locking part 14 maintains the tendency to slide towards the hook platform part 6.
[0089] This design makes the sliding block 11 more stable in both the locked and ejected states, preventing it from becoming loose.
[0090] That is, when the latch 5 acts in the locking insertion space 16, the elastic element 13 will always give the sliding block 11 a pushing force, so that the locking part 14 maintains the tendency to slide towards the hook platform part 6.
[0091] In some specific embodiments, the sliding block 11 has a limiting groove 18 on its side to limit the end of the elastic member 13, and a top rod 17 coaxially arranged with the elastic member 13 is provided in the limiting groove 18.
[0092] The presence of the push rod 17 and the limiting groove 18 can provide axial limiting when the elastic element 13 is compressed, ensuring that the direction of the elastic force applied by the elastic element 13 is always parallel to the sliding direction of the sliding block 11.
[0093] In some specific embodiments, the surface of the housing 1 also has a sliding guide groove 19, which is correspondingly provided with the mounting chamber 8. The sliding guide groove 19 has a long strip structure; the surface of the sliding block 11 is provided with a sliding knob 12 that is positioned and connected in the sliding guide groove 19.
[0094] The sliding guide groove 19 is designed to control the sliding distance of the sliding block 11.
[0095] In some specific embodiments, the length of the locking insertion space 16 is less than the maximum sliding stroke of the sliding dial 12 along the sliding guide groove 19.
[0096] If the size is greater than that, it is easy for the sliding dial 12 to slide from one end to the other in the sliding guide groove 19, but the ejector part 15 still does not eject the latch 5, that is, the battery cover 3 cannot achieve the operation of automatically popping out.
[0097] In some specific embodiments, the inner wall of the installation chamber 8 is provided with a guide strip 20, which is arranged parallel to the sliding direction of the sliding block 11, and the surface of the sliding block 11 is provided with a guide groove 21 that cooperates with the guide strip 20.
[0098] By cooperating with the guide bar 20 and the guide groove 21, not only can the stability of the sliding block 11 be improved when it slides, but the maximum sliding stroke of the sliding block 11 can also be further limited.
[0099] In some embodiments, the mounting chamber 8 has a socket 9, which is configured to guide the latch 5 into the locking insertion space 16 when the battery cover 3 is positioned and connected to the slot of the battery compartment 4.
[0100] With the above design, the latch 5 and the locking insertion space 16 will not easily misalign when they are matched.
[0101] That is, socket 9 will serve as a guide.
[0102] In some specific embodiments, a probe module 2 is provided at the end of the housing 1; the outer periphery of the housing 1 serves as a gripping part when using the probe module 2.
[0103] The probe module 2 is mainly used to measure temperature, which is existing technology and will not be described in detail here. Secondly, the outer periphery of the housing 1 is a conventional design for holding the probe module 2 when using it. The probe module 2 does not necessarily have to be designed at the end of the housing 1; it can also be set on the periphery of the housing 1.
[0104] Working principle:
[0105] From the perspective of sliding block 11, it can be divided into two states: locked state and ejected state.
[0106] Reference Figure 9 The hook platform 6 is provided with an inlet ramp on the side away from the battery cover 3 and a hook plane on the side closer to the battery cover 3.
[0107] In the locked state: The battery cover 3 is directly guided to the slot of the battery compartment 4. Then, the latch 5 is configured to act within the locking insertion space 16. When the latch 5 enters the locking insertion space 16, the locking part 14 first contacts the guide ramp on the hook platform 6. As the latch 5 continues to enter, the locking part 14 slides along the guide ramp. During this process, the sliding block 11 and the ejector part 15 also slide (to...). Figure 9 For reference, the locking part 14 slides down with the sliding block 11 and the ejector part 15, and guides the elastic element 13 (i.e., the spring) to start storing force.
[0108] Once the locking part 14 slides to the edge of the hook plane, the elastic element 13 returns to its original position. At this time, the ejector part 15 abuts against the ejector ramp 7, and the locking part 14 hooks the hook platform part 6 so that the battery cover 3 is fixed relative to the housing 1.
[0109] In the ejected state: simply push the sliding block 11 to slide it so that the locking part 14 just disengages from the hook platform part 6, and then continue to push the sliding block 11. After that, the ejecting part 15 pushes the latch 5 away from the housing 1 by sliding along the ejection ramp 7.
[0110] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
