Description

Technical Field

[0001] This application relates to the technical field of health temperature measurement components, and particularly to a handheld forehead thermometer. Background Art

[0002] A handheld forehead thermometer is an instrument that measures the human body temperature using the principle of infrared radiation. The handheld forehead thermometer measures the body temperature by receiving the infrared radiation energy emitted by the human body. After the infrared rays emitted by the object enter, they are received by the internal thermopile, and the thermopile converts the infrared rays into heat energy and then into an electrical signal. The electrical signal is finally converted into the temperature value on the screen. The handheld forehead thermometer has the characteristics of no laser point, no need to contact the human skin, etc., eliminating the potential harm to the eyes and avoiding contact infection, being convenient and fast.

[0003] The utility model patent publication number CN216021005U discloses a forehead thermometer convenient to hold, including a left housing. A right housing is arranged on one side of the left housing. A fixed box is fixed on the inner wall of the top of the left housing. Two insertion blocks are fixed on the inner wall of the top of the right housing, and the insertion blocks are all inserted into the inside of the fixed box. In this utility model, through the cooperation of the left housing, the right housing, the fixed box, the clamping component, the insertion blocks, the bidirectional lead screw, the L-shaped moving block, the worm, the worm gear and the arc-shaped plate, through the cooperation of the clamping component and the insertion blocks, when the electronic components inside the housing are damaged and need to be repaired or replaced, the disassembly and assembly of the left housing and the right housing can be more convenient. However, opening the forehead thermometer by disassembling the housing results in a large number of components that need to be connected and aligned during reinstallation, making the installation difficult and not conducive to the stable fixation of the internal components. Summary of the Invention

[0004] In order to solve the problem of unstable fixation of the internal components of a handheld forehead thermometer that can be separated and removed, this application provides a handheld forehead thermometer.

[0005] The handheld forehead thermometer provided by this application adopts the following technical solutions:

[0006] A handheld forehead thermometer includes:

[0007] A housing having a temperature measurement port and two oppositely arranged mounting ports;

[0008] A temperature measurement cover installed outside the temperature measurement port;

[0009] Two mounting blocks, which are respectively installed in the two mounting ports;

[0010] A detection mechanism including a circuit board and a temperature measurement component. The circuit board forms a clamping connection with the two mounting blocks to fix the circuit board inside the housing. The temperature measurement component is fixedly connected to the temperature measurement cover and is arranged inside the housing. The circuit board is electrically connected to the temperature measurement component.

[0011] By adopting the above technical solution, mounting blocks are installed in the mounting openings on both sides of the housing, so that the mounting blocks clamp and fix the circuit board from both sides. When the circuit board needs to be removed and replaced, the mounting blocks can be simply removed from the housing to complete the removal of the circuit board. While stably fixing the circuit board, the convenient removal of the circuit board can be achieved. And by fixing the temperature measuring component on the temperature measuring cover, when the temperature measuring cover and the housing are separated, the temperature measuring component can be separated together with the temperature measuring cover, facilitating the removal of the circuit board. And when the temperature measuring component needs to be adjusted, it can be directly adjusted on the temperature measuring cover, facilitating the adjustment and replacement of the internal structure of the handheld forehead thermometer.

[0012] Optionally, the housing has a first connection hole, and the temperature measuring cover has a first connecting rod. The first connection hole connects the first connecting rod to fix the housing and the temperature measuring cover.

[0013] By adopting the above technical solution, through the first connection hole, the connection with the first connecting rod can be completed by parts such as screws. While stably fixing the housing and the temperature measuring cover, it is convenient to separate the two.

[0014] Optionally, the temperature measuring cover has a second connecting rod, and the temperature measuring component has a second connection hole. The second connecting rod connects the second connection hole to fix the temperature measuring cover and the temperature measuring component.

[0015] By adopting the above technical solution, since the temperature measuring component usually has a small area and a thin thickness, the temperature measuring component is fixed through the second connection hole, so that the temperature measuring component can be stably fixed on the temperature measuring cover, and it is convenient to remove the temperature measuring component from the temperature measuring cover, making the replacement and adjustment of the temperature measuring component more convenient.

[0016] Optionally, it further includes a control component. The control component includes a button component. The housing also has a button opening. The button component is installed in the button opening and is connected to the circuit board.

[0017] By adopting the above technical solution, the button component is used to control the handheld forehead thermometer to perform body temperature detection. The button component is arranged in the button opening and is not connected to the housing, making the button component easy to separate and facilitating the disassembly of the button component from the housing.

[0018] Optionally, the housing includes a front cover and a rear cover. The front cover has a third connecting rod, and the rear cover has a third connection hole. The third connecting rod connects the third connection hole to fix the front cover and the rear cover.

[0019] By adopting the above technical solution, since there are other components in the housing that cannot be separated from the temperature measuring port, the housing needs to be divided into a separable front cover and rear cover, so that the remaining components in the housing can be separated and replaced, improving the applicability of the handheld forehead thermometer.

[0020] Optionally, the circuit board has a limit hole, the third connecting rod passes through the limit hole, and a limit strip is provided on the outer side of the third connecting rod. The limit strip abuts against the circuit board to prevent the circuit board from sliding relative to the third connecting rod.

[0021] By adopting the above technical solution: on the one hand, the limit hole can limit the movement of the circuit board in the vertical direction by passing through the third connecting rod, and a positioning strip is provided on the outer edge of the third connecting rod. The limit hole cannot allow the limit strip to pass through. Therefore, when the limit strip abuts against the circuit board, the movement of the circuit board in the direction of the limit strip is restricted.

[0022] Optionally, the mounting block has a protrusion. When the mounting block is snap-connected to the circuit board, the protrusion is located on one side of the circuit board relative to the limit strip to cooperate with the limit strip to fix the circuit board.

[0023] By adopting the above technical solution, the protrusion cooperates with the limit strip. After the circuit board is fixed to the third connecting rod and the mounting block respectively, the other side of the circuit board relative to the limit strip is abutted by the protrusion, restricting the movement of the circuit board in the direction of the protrusion. Thus, the circuit board is clamped by the protrusion and the limit strip, restricting the movement of the circuit board in two directions, fixing the circuit board in the housing, and ensuring the stability of the circuit board during use.

[0024] Optionally, the control assembly further includes a display screen and a button. The display screen and the button are both provided on the rear cover and are both electrically connected to the circuit board.

[0025] By adopting the above technical solution, the display screen and the button can perform more detailed control on the handheld forehead thermometer. The display screen and the button are provided on the rear cover, enabling the operator to conveniently obtain information from the display screen when the temperature measuring component is measuring the temperature.

[0026] In summary, the present application includes at least one of the following beneficial technical effects:

[0027] 1. By installing the mounting blocks in the mounting openings on both sides of the housing, the mounting blocks are used to snap-fix the circuit board from both sides. When the circuit board needs to be removed and replaced, the circuit board can be removed by simply removing the mounting blocks from the housing. While stably fixing the circuit board, the convenient removal of the circuit board can be achieved.

[0028] 2. The limiting hole can, on the one hand, pass through the third connecting rod to limit the movement of the circuit board in the vertical direction. A positioning strip is provided on the outer edge of the third connecting rod, and the limiting hole cannot allow the limiting strip to pass through. Thus, when the limiting strip abuts against the circuit board, the movement of the circuit board in the direction of the limiting strip is restricted; the protruding part cooperates with the limiting strip. After the circuit board is fixed to the third connecting rod and the mounting block respectively, the other side of the circuit board relative to the limiting strip is abutted by the protruding part, restricting the movement of the circuit board in the direction of the protruding part. Thus, the circuit board is clamped by the protruding part and the limiting strip, restricting the movement of the circuit board in two directions and fixing the circuit board in the housing to ensure the stability of the circuit board during use.

Detailed Description of the Embodiment

[0033] The following will further describe the present application in detail with reference to the accompanying drawings.

[0034] A handheld forehead thermometer, referring to Figure 1 and Figure 2, including a housing 1, a temperature measurement cover 2, a mounting block 3, a detection mechanism 4 and a control component 5. The housing 1 includes a front cover 11 and a rear cover 12. The front cover 11 has a third connecting rod 17, and the rear cover 12 has a third connecting hole 18. The third connecting rod 17 and the third connecting hole 18 are arranged opposite to each other. When connecting the third connecting rod 17 and the third connecting hole 18 with parts such as screws, the fixation between the front cover 11 and the rear cover 12 is achieved. A temperature measurement port 13 and two oppositely arranged mounting ports 14 are provided on the front cover 11. The temperature measurement cover 2 covers the outside of the temperature measurement port 13. The housing 1 has a first connecting hole 16, and the temperature measurement cover 2 has a first connecting rod 21. The first connecting hole 16 can be connected to the first connecting rod 21 through structures such as screws or snap connections to achieve the fixation between the housing 1 and the temperature measurement cover 2. The mounting block 3 can be pressed into the mounting port 14 to complete the fixation between the mounting block 3 and the housing 1. In addition, the holding part of the housing 1 is provided with friction lines 19. The friction lines 19 are respectively arranged on the front cover 11 and the rear cover 12, which can increase the friction between the holding part and the palm, making it more stable for the user to hold the forehead thermometer, not easy to slip, and improving the operation stability of the forehead thermometer.

[0035] Refer to Figure 2 , the detection mechanism 4 includes a circuit board 41 and a temperature measurement component 42. The edge of the circuit board 41 has an inwardly recessed opening, and two mounting blocks 3 partially protrude into the front cover 11. The protruding part of the mounting block 3 fits with the edge opening of the circuit board 41 to form a snap connection. The circuit board 41 forms snap connections with the mounting blocks 3 on both sides, and then the mounting blocks 3 fix the circuit board 41 in the front cover 11. This fixing method is achieved by the mounting block 3 being snapped into the mounting port 14, and the mounting block 3 also forms a snap connection with the circuit board 41. When it is necessary to disassemble the circuit board 41, just take out the mounting block 3 to separate the circuit board 41 and the front cover 11 and take out the circuit board 41 from the front cover 11. A limiting hole 43 is provided on the circuit board 41. The third connecting rod 17 passes through the limiting hole 43, and a limiting strip 17a is provided on the side wall of the third connecting rod 17. The limiting strip 17a cannot pass through the limiting hole 43, so as to limit the movement of the circuit board 41 in the direction of the limiting strip 17a. A protruding part 31 is provided on the mounting block 3 on the side of the circuit board 41 opposite to the limiting strip 17a. The protruding part 31 and the limiting strip 17a clamp the circuit board 41 from both sides to fix the circuit board 41 in the front cover 11. The fixing block can also ensure the stable installation of the circuit board 41 and ensure the normal operation of the forehead thermometer.

[0036] Refer to Figure 2, the temperature measuring component 42 is fixedly connected to the temperature measuring cover 2. After the temperature measuring cover 2 is connected to seal the temperature measuring port 13, the temperature measuring component 42 is fixed inside the housing 1. The temperature measuring cover 2 has an opening for the temperature measuring component 42 to pass through for measuring the outside. Therefore, the connection between the temperature measuring cover 2 and the temperature measuring component 42 is relatively tight. By fixing the temperature measuring component 42 on the temperature measuring cover 2, when disassembling or installing, the temperature measuring component 42 can be taken out or inserted together with the temperature measuring cover 2, maintaining the stability of the connection between the temperature measuring component 42 and the temperature measuring cover 2. The temperature measuring cover 2 also has a second connecting rod 22, and the temperature measuring component 42 has a second connecting hole. The second connecting rod 22 connects the second connecting hole 44, thereby fixing the temperature measuring cover 2 and the temperature measuring component 42 and ensuring the stable connection between the temperature measuring component 42 and the temperature measuring cover 2. The circuit board 41 is electrically connected to the temperature measuring component 42 and is used to receive and process the signal of the temperature measuring component 42. When disassembling the handheld forehead thermometer and separating the circuit board 41 and the temperature measuring component 42, only need to pull out the connection plug or wire connector to simply separate the two.

[0037] Refer to Figure 3 , the handheld forehead thermometer further includes a control component 5, and the control component 5 includes a button component 51. The housing 1 also has a button port 15, and the button component 51 is installed in the button port 15 and is connected to the circuit board 41. Through the button component 51, the user can conveniently operate the handheld forehead thermometer, such as starting measurement, switching modes, etc.

[0038] Refer to Figure 3 , the control component 5 further includes a display screen 52 and a button 53. The display screen 52 and the button 53 are provided on the back of the rear cover 12 and are electrically connected to the circuit board 41. The display screen 52 can display the measured body temperature data in real time, enabling the user to intuitively understand the measurement result. The button 53 can be used by the operator to adjust the display content of the display screen 52 or the working mode of the handheld forehead thermometer, making the handheld forehead thermometer have more applicable scenarios.

[0039] The implementation principle of the embodiment of this application is: when using the handheld forehead thermometer, hold the handheld part of the housing 1, align the detection head of the temperature measuring component 42 with the forehead of the person to be measured, and after starting through the button component 51, the detection information can be output through the display screen 52. When it is necessary to adjust the temperature measuring component 42, disassemble the housing 1 and the temperature measuring cover 2, so that the temperature measuring component 42 can be adjusted on the temperature measuring cover 2. When it is necessary to adjust the circuit board 41, disassemble the front cover 11 and the rear cover 12, take out the mounting block 3, and remove the circuit board 41 from the third connecting rod 17, so that while stably fixing the circuit board, the convenient removal of the circuit board can be achieved.

[0040] The embodiments of this specific implementation manner are all preferred embodiments of this application, and do not limit the protection scope of this application accordingly. The same components are denoted by the same reference numerals. Therefore: all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
