When users are working outdoors, conducting laboratory tests, or cooking in the kitchen, they often need to operate the thermometer with one hand. They must first completely remove the thermometer from its protective cover, a step that is particularly cumbersome when holding other items or wearing gloves. In wet, greasy, or fast-measuring work environments, removing the device not only wastes time but also increases the risk of slipping and falling. This inconvenience directly affects work efficiency, especially in situations requiring frequent and continuous measurements. The repeated process of taking the device out and putting it back in severely reduces the user experience. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a portable water thermometer with digital display. Through a protective and quick-lock structure, it enables one-click rapid deployment and stable measurement of the water thermometer. Its integrated protection ensures that the device is effectively dustproof, impactproof, and moistureproof when carried and stored, improving its durability, measurement reliability, and ease of use in complex environments.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a portable water thermometer with a digital display, comprising a detection mechanism for measuring liquid temperature, the detection mechanism comprising: The protective assembly includes a ring seat fixed at the lower end of the inner shell, a fastening sleeve installed at the bottom of the ring seat and located at the lower end of the inner shell, a number of circumferentially arranged slots on the fastening sleeve, a clamping sleeve fitted on the lower end of the fastening sleeve and located at the lower end of the inner shell, and the outer wall of the clamping sleeve is threaded to the inner wall of the inner shell, and a knob is fixed at the bottom of the clamping sleeve. The temperature measuring component includes a water thermometer body installed inside the cylindrical shell, an extension sleeve fixed to the lower end of the water thermometer body, a detection head installed at the lower end of the extension sleeve, a digital display screen installed at the front end of the water thermometer body, a switch installed above the front end of the water thermometer body, and grooves opened on the outer walls of both ends of the water thermometer body.

[0005] Preferably, the protective component further includes a soft rubber strip fixed to the outer wall of the knob, with a rubber plug fixed to the other end of the soft rubber strip, and a sponge head fixed to the inner surface of the rubber plug.

[0006] Preferably, the protective component further includes a button that is slidably mounted through the front end of the cylindrical shell, and a transparent window is fixed to the front end of the cylindrical shell.

[0007] Preferably, the protective assembly further includes protrusions fixed to the inner walls at both ends of the cylindrical shell and cooperating with the grooves.

[0008] Preferably, the protective assembly further includes a cylinder cover installed on the upper end of the cylinder shell, and the inner wall of the cylinder cover is threadedly installed with the outer wall of the cylinder shell.

[0009] Preferably, the protective component further includes a lobster buckle fixed to the upper end of the cap.

[0010] Beneficial effects This invention provides a portable water thermometer with a digital display. Compared with the prior art, it has the following advantages: 1. When needed, pull the rubber stopper out of the knob. At this time, the temperature measuring component will automatically fall down along the inside of the cylinder under the action of gravity until the thermometer body is limited by the ring seat. At this time, the measuring head just passes through the center hole of the knob and extends to the outside. Then rotate and tighten the knob, which will drive the clamping sleeve fixed therein to screw upward by means of the thread engagement with the inner wall of the cylinder. The conical inner wall of the clamping sleeve will then radially squeeze the fastening sleeve with several slots, forcing the fastening sleeve to produce elastic deformation and shrink its inner diameter, thereby firmly clamping the extension sleeve. This prevents it from loosening due to shaking or pulling during the measurement process, ensuring the stability and reliability of the measurement.

[0011] 2. When not in use, the temperature measuring component can be completely retracted into the cylinder shell, and then the rubber stopper can be inserted into the through hole in the center of the knob, so that the sponge head fixed inside the rubber stopper can directly contact the lower end of the exposed detection head; this prevents dust, moisture and other contaminants from entering the cylinder shell through this inlet. In addition, when the sponge head contacts the detection head, it acts as a buffer to prevent the detection head from being damaged by rigid collision or friction with the hard rubber stopper when it is in the retracted state.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1 - Figure 5 This utility model provides a technical solution: a portable water thermometer with digital display, including a detection mechanism 1 for measuring liquid temperature, the detection mechanism 1 including: The protective component 11 includes a ring seat 112 fixed inside the lower end of the cylindrical shell 111. A fastening sleeve 113 is installed at the bottom of the ring seat 112 and is located inside the lower end of the cylindrical shell 111. The fastening sleeve 113 has several circumferentially arranged slots 114. A clamping sleeve 115 is sleeved on the lower end of the fastening sleeve 113 and is located inside the lower end of the cylindrical shell 111. The outer wall of the clamping sleeve 115 is threaded to the inner wall of the cylindrical shell 111. A knob 116 is fixed at the bottom of the clamping sleeve 115. The temperature measuring component 12 includes a water thermometer body 121 installed inside the cylindrical shell 111. An extension sleeve 122 is fixed to the lower end of the water thermometer body 121. A detection head 123 is installed at the lower end of the extension sleeve 122. A digital display screen 124 is installed at the front end inside the water thermometer body 121. A switch 125 is installed above the front end of the water thermometer body 121. Grooves 126 are provided on the outer walls at both ends of the water thermometer body 121.

[0016] In this embodiment, when needed, the rubber stopper 118 is pulled out of the knob 116. At this time, the temperature measuring component 12 automatically falls down along the inside of the cylinder shell 111 under the action of gravity until the water thermometer body 121 is limited by the ring seat 112. At this time, the detection head 123 just passes through the central hole of the knob 116 and extends to the outside. Then, the knob 116 is rotated and tightened, which drives the clamping sleeve 115 fixed thereto to screw upward by means of the threaded engagement with the inner wall of the cylinder shell 111. The conical inner wall of the clamping sleeve 115 then radially squeezes the fastening sleeve 113 with several slots 114, forcing the fastening sleeve 113 to undergo elastic deformation and inner diameter contraction, thereby firmly clamping the extension sleeve 122. This prevents loosening due to shaking or pulling during the measurement process and ensures the stability and reliability of the measurement.

[0017] Specifically, the protective component 11 also includes a soft rubber strip 117 fixed to the outer wall of the knob 116, and a rubber plug 118 fixed to the other end of the soft rubber strip 117. A sponge head 119 is fixed to the inner surface of the rubber plug 118.

[0018] In this embodiment, when not in use, the temperature measuring component 12 can be completely retracted into the cylinder shell 111, and then the rubber stopper 118 can be inserted into the through hole in the center of the knob 116, so that the sponge head 119 fixed inside the rubber stopper 118 directly contacts the lower end of the exposed detection head 123; preventing dust, moisture and other contaminants from entering the cylinder shell 111 through the inlet, and when the sponge head 119 contacts the detection head 123, it acts as a buffer to prevent the detection head 123 from being rigidly impacted or rubbed against the hard rubber stopper 118 in the retracted state, thus avoiding damage.

[0019] Specifically, the protective component 11 also includes a button 1110 that is slidably mounted through the front end of the cylindrical shell 111, and a transparent window 1111 is fixed to the front end of the cylindrical shell 111.

[0020] In this embodiment, when the temperature measuring component 12 is extended into its working state, the switch 125 on the thermometer body 121 is aligned with the button 1110 on the casing 111. The internal switch 125 can be operated indirectly by pressing the button 1110 externally without completely removing the temperature measuring component 12 from the protective casing 111. At the same time, its digital display screen 124 is located behind the visible area of ​​the transparent window 1111, and the data on the digital display screen 124 can be clearly read through the transparent window 1111.

[0021] Specifically, the protective component 11 also includes protrusions 1112 fixed to the inner walls of both ends of the cylindrical shell 111 and cooperating with the grooves 126.

[0022] In this embodiment, the sliding engagement of the protrusion 1112 and the groove 126 restricts the circumferential rotation of the thermometer body 121 inside the shell 111, ensuring that its switch 125 and digital display screen 124 can always be accurately aligned with the external button 1110 and transparent window 1111; and the movement of the temperature measuring component 12 is strictly limited to the linear movement range along the axis of the shell 111, so that it can automatically and smoothly reach the preset measurement position when falling.

[0023] Specifically, the protective component 11 also includes a cover 1113 installed on the upper end of the shell 111, and the inner wall of the cover 1113 is threadedly installed on the outer wall of the shell 111.

[0024] In this embodiment, when maintenance, cleaning or battery replacement is required, the user only needs to unscrew the cap 1113 to smoothly remove the entire temperature measuring component 12 from above the shell 111. After maintenance, the component is put back and the cap 1113 is tightened again.

[0025] Specifically, the protective component 11 also includes a lobster buckle 1114 fixed to the upper end of the cap 1113.

[0026] In this embodiment, the spring mechanism of the lobster clip 1114 allows users to easily operate with one hand and quickly hang the entire thermometer at the desired location, achieving convenient portability in various usage scenarios.

[0027] The working principle and usage process of this utility model are as follows: First, when needed, the rubber stopper 118 is pulled out from the knob 116. At this time, the temperature measuring component 12 automatically falls down along the inside of the cylinder shell 111 under the action of gravity until the water thermometer body 121 is limited by the ring seat 112. At this time, the detection head 123 just passes through the central hole of the knob 116 and extends to the outside. Then, the knob 116 is rotated and tightened, which drives the clamping sleeve 115 fixed thereto to be screwed upward by the threaded engagement with the inner wall of the cylinder shell 111. The conical inner wall of the clamping sleeve 115 then radially squeezes the fastening sleeve 113 with several slots 114, forcing the fastening sleeve 113 to undergo elastic deformation and shrink its inner diameter, thereby firmly clamping the extension sleeve 122. This prevents loosening due to shaking or pulling during the measurement process and ensures the stability and reliability of the measurement. When not in use, the temperature measuring component 12 can be completely retracted into the shell 111, and the rubber stopper 118 can be inserted into the through hole in the center of the knob 116, so that the sponge head 119 fixed inside the rubber stopper 118 can directly contact the lower end of the exposed detection head 123; this prevents dust, moisture and other contaminants from entering the shell 111 through the inlet, and the sponge head 119 acts as a buffer pad when it contacts the detection head 123 to prevent the detection head 123 from being rigidly impacted or rubbed against the hard rubber stopper 118 in the retracted state, thus avoiding damage.
