[0029] The technical scheme in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. The specific structural and functional details disclosed here are only representative and are for the purpose of describing the exemplary embodiments of the utility model. However, the utility model can be specifically implemented in many alternative forms and should not be interpreted as being limited to the embodiments described here. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of this protection.

[0030] Reference Figure 1 , Figure 2 As shown, the embodiment of the utility model provides a thermometer 1. The thermometer 1 includes, for example, a thermometer body 100 and a protective member 200.

[0031] Specifically, Figure 1 , Figure 2 , Figure 3 As shown, the thermometer body 100 is, for example, a transparent thermometer of a columnar structure, such as a glass thermometer. The thermometer body 100 may be, for example, a cylindrical structure, and the thermometer body 100 includes a first end 101 and a second end 102 that are arranged opposite to each other, and the cross-sectional area of ​​the first end 101 is smaller than that of the second end 102. A mercury containing chamber 110 is provided inside the thermometer body 100, and the mercury containing chamber 110 extends, for example, along a first direction X from the first end 103 to the second end 104, and the mercury containing chamber 110 is used to accommodate mercury, for example. A limiting portion 120 is provided at the first end 101 of the thermometer body 100, and the cross-sectional area of ​​the limiting portion 120 gradually increases along the first direction X toward the second end 102. A temperature probe 140 is also provided on the first end 101, and the temperature probe 140 is located on the side of the limiting portion 120 away from the second end 102. The temperature probe 140 is used to detect the temperature of a part of the human body.

[0032] The protective member 200 is, for example, a rectangular shell or a cylindrical shell. The protective member 200 is, for example, formed by two opposite halves of a rectangular shell fixedly connected. Such an arrangement can facilitate the disassembly and assembly of the thermometer body 100. The protective member 200 includes a third end 203 and a fourth end 204 arranged relatively along a first direction X. The third end 203 is provided with a first through hole 201. The internal cavity of the protective member 200 is provided with a protective cavity 202 along the first direction X. The protective cavity 202 is connected to the first through hole 201. The protective cavity 202 is, for example, a cylindrical cavity. The thermometer body 100 is, for example, movably connected in the protective cavity 202, and the protective member 200 is used to protect the thermometer body 100. The first end 101 corresponds to the third end 203, and the second end 102 corresponds to the fourth end 204. The thermometer body 100 can slide in the protective cavity 202 along the first direction X relative to the protective member 200. When the thermometer body 100 slides toward the first through hole 201, see Figure 1 , Figure 2As shown, the temperature probe 140 of the thermometer body 100 can extend out of the first through hole 201, and the thermometer is in an extended state at this time. At this time, the limit portion 120 abuts against the first through hole 201, so that the thermometer body 100 will not be separated from the protective cavity 202. At this time, the user can use the thermometer to measure the temperature of the human body. In addition, the protective member 200 does not need to be removed during the use of the thermometer 1, which is convenient to use and avoids the loss of the protective member 200 during use, thereby ensuring that the protective member 200 can still protect the thermometer body 100 during use and prevent the thermometer body 100 from being accidentally broken during use.

[0033] Specifically, Figure 3 , Figure 4 As shown, the surface of the thermometer body 100 is marked with a plurality of scales 130 arranged in sequence along the first direction X, and the plurality of scales 130 are arranged opposite to the mercury receiving cavity 110, so that the user can observe and read the mercury in the mercury receiving cavity 110. The surface of the protective member 200 is provided with a first observation window 205 connected to the protective cavity 202, and the first observation window 205 corresponds to the plurality of scales 130, so that the user can observe the plurality of scales 130 through the first observation window 205 and read the mercury.

[0034] Further, see Figure 5 As shown, the surface of the protective member 200 is also provided with a second observation window 206, and the second observation window 206 is arranged relative to the first observation window 205. The second observation window 206 is connected to the protective cavity 202 to prevent the protective member 200 from blocking external light and hindering the user from observing the mercury position and scale on the thermometer body 100. By providing the second observation window 206, light can enter the protective cavity 202 through the second observation window 206, so that the user can clearly see the mercury position and the corresponding scale. Of course, the user can also observe the mercury position and scale through the second observation window 206, and the first observation window 205 is used for the entry of light.

[0035] Furthermore, if Figure 6 , Figure 7 , Figure 8 and Fig. 9As shown, the thermometer 1 also includes a sliding member 300. The sliding member 300 is arranged in the protective cavity 202. The sliding member 300 is, for example, arranged between the fourth end 204 and the second end 102. The sliding member 300 is used to push the thermometer body 100 to slide in the protective cavity 202. Specifically, the sliding member 300 is, for example, a sliding member made of elastic plastic material. The sliding member 300 includes a first connecting portion 301, and a first operating portion 302 and a second operating portion 303 connected to opposite ends of the first connecting portion 301. The first operating portion 302 and the second operating portion 303 are respectively arranged on opposite sides of the surface of the protective member 200. For example, a notch connecting the protective cavity 202 is provided on the protective member 200, so that the opposite ends of the first connecting portion 301 pass through the protective member 200 and connect the first operating portion 302 and the second operating portion 303. The first operating portion 302, the second operating portion 303 and the first connecting portion 301 form an H-shaped structure, for example. The first connection portion 301 can be driven by the first operating portion 302 and the second operating portion 303 to slide along the first direction X in the protection cavity 202 . The first connection portion 301 is fixedly connected to the second end 102 of the thermometer body 100 . The surface of the protective member 200 is, for example, provided with a limit groove 207, and the first operating part 302 and the second operating part 303 are both provided with a limit tenon 304, and the limit tenon 304 corresponds to the limit groove 207. The user can drive the thermometer body 100 to switch between the retracted state and the extended state through the first operating part 302 and the second operating part 303. For example, when the thermometer body 100 is in the extended state, the limit tenon 304 is stuck in the limit groove 207, thereby fixing the position of the thermometer body 100; in addition, the user can operate the first operating part 302 and the second operating part 303 at the same time to cause a slight deformation of the first connecting part 301, thereby causing the limit tenon 304 to disengage from the limit groove 207, so that the thermometer body 100 can move relative to the protective member 200.

[0036] Furthermore, if Figure 8 , Fig. 9 As shown, the thermometer 1 further includes an elastic member 400 disposed in the protective cavity 202, such as a spring, and the elastic member 400 is located between the sliding member 300 and the fourth end 204. The two ends of the elastic member 400 are connected to the sliding member 300 and the protective member 200 in a one-to-one correspondence, so as to provide the sliding member 300 with a force along the first direction X. When the thermometer 1 is in the extended state, the user can operate the first operating part 302 and the second operating part 303 to disengage the limiting latch 304 from the limiting groove 207. At this time, the elastic force of the elastic member 400 drives the sliding member 300 and the thermometer body 100 to slide toward the fourth end 204. At this time, the thermometer 1 is in the retracted state. In this way, the temperature probe 140 can be prevented from sliding at will, and the thermometer body 100 is protected.

[0037] In one embodiment of the present invention, Fig.10 , Fig.11 , Fig.12 , Fig.13 As shown, the sliding member 300 is, for example, a cylindrical structure, and the sliding member 300 also includes, for example, a second connecting portion 310 and a third operating portion 320 which are sequentially arranged along the first direction X. The second connecting portion 310 is movably connected in the protective cavity 202 and fixedly connected to the second end 102 of the thermometer body 100, and the fourth end 204 is, for example, provided with a second through hole 209, and the third operating portion 320 extends into the protective cavity 202 through the second through hole 209 along the first direction X and connects to the second connecting portion 310, and the user can drive the second connecting portion 310 and the thermometer body 100 by pushing the third operating portion 320 along the first direction. The surface of the second connecting portion 310 has, for example, a first clamping groove 311, a movable groove 312, and a second clamping groove 313 which are sequentially connected along the first direction X, wherein the movable groove 312 extends, for example, along the first direction X, and the first clamping groove 311 and the second clamping groove 313 are respectively connected to the two ends of the movable groove 312. The first clamping groove 311 and the second clamping groove 313 extend in directions perpendicular to the first direction X, respectively. The extension directions of the first clamping groove 311 and the second clamping groove 313 can be the same or opposite. The protective member 200 is provided with a clamping portion 208 in the protective cavity 202, and the clamping portion 208 is clamped in one of the first clamping groove 311, the movable groove 312 and the second clamping groove 313. The clamping portion 208 can slide with the sliding member 300 between the first clamping groove 311, the movable groove 312 and the second clamping groove 313, so that the sliding member 300 and the thermometer body 100 are clamped in the protective cavity 202. The user can control the second connecting portion 310 and the thermometer body 100 to slide in the protective cavity 202 through the third operating portion 320, so that the clamping portion 208 slides between the first clamping groove 311, the movable groove 312 and the second clamping groove 313. When the locking portion 208 slides and is locked in the first locking groove 311, for example, the locking portion 208 can fix the thermometer 1 in a retracted state; when the locking portion 208 slides and is locked in the second locking groove 313, for example, the locking portion 208 can fix the thermometer 1 in an extended state, which is convenient for users to use.

[0038] Furthermore, if Fig.12 , Fig.13As shown, the elastic member 400 is, for example, located between the sliding member 300 and the fourth end 204, and its two ends are connected to the second connecting portion 310 and the fourth end 204 of the protective member 200 in a one-to-one correspondence, so as to provide the sliding member 300 with a force in the first direction X. When the thermometer 1 is in the extended state, the user can operate the third operating portion 320 to make the locking portion 208 disengage from the second locking groove 313 and enter the movable groove 312. At this time, the elastic force of the elastic member 400 drives the sliding member 300 and the thermometer body 100 to slide toward the fourth end 204, and the locking portion 208 slides along the movable groove 312 to the first locking groove 311. At this time, the thermometer 1 is in the retracted state, so that the thermometer body 100 can be protected. In addition, when the thermometer 1 is in the retracted state, the user can operate the third operating portion 320 to make the locking portion 208 slide in the first locking groove 311 to the side away from the movable groove 312, thereby preventing the temperature probe 140 from sliding at will.

[0039] In one embodiment of the present invention, Figure 3 , Figure 8 As shown, the temperature probe 140 is, for example, a metal temperature probe, and a mercury storage chamber 150 is provided in the temperature probe 140, in which the mercury is stored, and the mercury storage chamber 150, for example, extends along the first direction X and is connected to the mercury storage chamber 150. When the user uses the thermometer 1 to measure the body temperature, for example, the temperature probe 140 is pressed against the armpit, and the body heat is transferred to the mercury in the mercury storage chamber 150 through the temperature probe 140. The mercury expands due to the heat and is filled into the mercury storage chamber 110 and stops at the corresponding position. The user can observe the position of the mercury and read the corresponding scale to obtain the temperature of the armpit.

[0040] In one embodiment of the present invention, Fig.14 As shown, the thermometer 1 also includes a connecting belt 500, which is, for example, a wristband made of soft rubber material, and the connecting belt 500 is connected to the fourth end 204 of the protective member 200. The user can use the connecting belt 500 to put the thermometer 1 on the wrist, for example. When the user uses the thermometer 1 and resets the mercury in the thermometer 1, since the reset operation requires the thermometer 1 to be swung, the connecting belt 500 can prevent the thermometer 1 from accidentally falling out of the user's hand during the reset operation and causing damage. In addition, the user can first switch the thermometer 1 to the retracted state, and then perform the reset operation, so as to prevent the temperature probe 140 from accidentally colliding with other objects when in the extended state.

[0041] The thermometer provided by the embodiment of the utility model has the protective member with the protective cavity provided therein, the thermometer body is movably provided in the protective cavity, and a limiting portion is provided at the first end of the thermometer body to correspond to the first through hole of the protective member, so as to prevent the thermometer body from being detached from the protective member through the first through hole, thereby avoiding the protective member from being lost during use, ensuring the safety of the thermometer body, and preventing the thermometer body from being accidentally broken during use; in addition, the surface of the protective member is provided with the first observation window corresponding to the plurality of scales, and even the second observation window corresponding to the plurality of scales. The thermometer body is provided with an observation window, which is convenient for the user to observe the scale corresponding to the mercury position for reading; in addition, by arranging the sliding member connected to the thermometer body inside the thermometer body, the user can conveniently control the temperature probe of the thermometer body to extend or retract into the protective cavity through the sliding member, and the elastic member is arranged in the protective cavity, and the sliding member is driven by the elastic force of the elastic member, so that the temperature probe can automatically pop out of the protective cavity; in addition, a connecting belt is also arranged on the protective member, which is used for the user to put the connecting belt on the hand for operation, so as to prevent the thermometer from accidentally falling out of the user's hand when the user operates the thermometer.
