Description

Technical Field

[0001] This utility model relates to the field of temperature measurement equipment technology, specifically to an adsorption-type fireplace pointer thermometer. Background Technology

[0002] As a common heating device, monitoring the surface temperature of fireplaces is of great significance for safe use and energy efficiency control.

[0003] Traditional fireplace thermometers are mostly wall-mounted, requiring drilling holes in the fireplace or wall for installation. This is not only cumbersome but also easily damages the structural integrity of the fireplace.

[0004] A few thermometers are fixed by hanging or placing, which can lead to unstable installation, easy displacement or falling, affecting the accuracy and reliability of temperature measurement. In particular, when the fireplace surface is uneven or there is vibration, the thermometer is not in close contact with the fireplace, resulting in reduced heat conduction efficiency, delayed temperature response, and even reading errors. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides an adsorption-type fireplace pointer thermometer, which can effectively solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] This utility model provides an adsorption-type fireplace pointer thermometer, including: a thermometer body and a magnetic attraction component. The thermometer body and the magnetic attraction component are connected by an elastic connector. The thermometer body includes a shell, a transparent mirror is fixedly connected to one end of the shell, and a receiving cavity is fixedly connected to the other end of the shell. A bimetallic strip and a pointer component are disposed inside the receiving cavity. A scale is fixedly connected inside the shell, and a heat-conducting plate is fixedly connected to the surface of the receiving cavity. The magnetic attraction component includes a magnetic base, and a permanent magnet is disposed inside the magnetic base.

[0008] Furthermore, a handle is rotatably connected to the side wall of the shell, a fixing pin is fixedly connected to one side of the cavity, and a rotating shaft is fixedly connected to the middle of the cavity.

[0009] Furthermore, the pointer assembly includes a rotating base, with a rotating hole in the center of the bottom end of the rotating base, and the rotating hole is rotatably connected to the rotating shaft.

[0010] Furthermore, a slot is provided on one side of the rotating seat, one end of the bimetallic strip is engaged inside the slot, and the other end of the bimetallic strip is engaged inside the fixed pin. A pointer is fixedly connected to the top of the rotating seat.

[0011] Furthermore, the permanent magnet is embedded inside the magnetic base, and an anti-slip rubber pad is fixedly connected to the side of the magnetic base that contacts the fireplace. The anti-slip rubber pad is slightly lower than the heat-conducting plate.

[0012] Furthermore, the elastic connector includes a groove and a connecting rod. The groove is formed on the surface of the other side of the magnetic base. Several grooves are provided and are distributed circumferentially on the surface of the magnetic base.

[0013] Furthermore, the connecting rod is fixedly connected to the housing, and there is a one-to-one correspondence between the connecting rod and the slide groove. The other end of the connecting rod is fixedly connected to a limit block, which is slidably connected inside the slide groove.

[0014] Furthermore, a spring is fitted onto the surface of the connecting rod, with one end of the spring abutting against one end of the slide groove and the other end of the spring abutting against one side of the limiting block.

[0015] The technical solution provided by this utility model has the following advantages compared with the known prior art:

[0016] 1. With the magnetic attachment component, the permanent magnet in the component can firmly attach the thermometer to the metal surface of the fireplace during use, eliminating the need to drill holes in the fireplace or wall. Installation and removal are convenient and quick, avoiding damage to the structural integrity of the fireplace;

[0017] 2. The heat-conducting plate directly contacts the fireplace surface, and the pressure of the elastic connector ensures a tight fit, which effectively improves the heat transfer efficiency. The bimetallic temperature sensing element responds sensitively to temperature changes, causing the pointer to deflect precisely. Combined with the clear scale, it ensures the accuracy and reliability of the temperature reading.

[0018] 3. With the flexible connector, the thermometer body has a certain degree of self-adaptability during use. Even if there is slight unevenness or vibration on the fireplace surface, the spring can continue to provide pressure to ensure good contact between the heat conduction plate and the fireplace surface. At the same time, the anti-slip rubber pad on the magnetic base further increases the stability of the adsorption and prevents sliding and displacement. Attached Figure Description

[0031] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0032] The present invention will be further described below with reference to the embodiments.

[0033] Example 1:

[0034] Reference Figure 1-9 The first embodiment of this utility model discloses an adsorption-type fireplace pointer thermometer, including: a thermometer body 1 and a magnetic suction assembly 2. The thermometer body 1 and the magnetic suction assembly 2 are connected by an elastic connector 3. The thermometer body 1 includes a housing 101. A transparent mirror 102 is fixedly connected to one end of the housing 101, and a receiving cavity 103 is fixedly connected to the other end of the housing 101. A bimetallic strip 104 and a pointer assembly 105 are disposed inside the receiving cavity 103. A scale 106 is fixedly connected inside the housing 101. A heat-conducting plate 108 is fixedly connected to the surface of the receiving cavity 103. The magnetic suction assembly 2 includes a magnetic suction base 201. A permanent magnet 202 is disposed inside the magnetic suction base 201.

[0035] With the magnetic component 2 in place, the permanent magnet 202 in the magnetic component 2 can firmly attach the thermometer body 1 to the metal surface of the fireplace when in use, without the need to drill holes in the fireplace or wall. Installation and disassembly are convenient and quick, avoiding damage to the structural integrity of the fireplace.

[0036] Example 2:

[0037] Reference Figure 1-9 This is the second embodiment of the present invention, which differs from the first embodiment in that:

[0038] A handle 107 is rotatably connected to the side wall of the housing 101. A fixing pin 1031 is fixedly connected to one side of the cavity 103. A rotating shaft 1032 is fixedly connected to the middle of the cavity 103. The pointer assembly 105 includes a rotating seat 1051. A rotating hole 1052 is opened in the middle of the bottom end of the rotating seat 1051. The rotating hole 1052 is rotatably connected to the rotating shaft 1032. A slot 1053 is opened on one side of the rotating seat 1051. One end of the bimetallic strip 104 is engaged in the slot 1053. The other end of the bimetallic strip 104 is engaged in the fixing pin 1031. A pointer 1054 is fixedly connected to the top of the rotating seat 1051. A permanent magnet 202 is embedded in the magnetic base 201. An anti-slip rubber pad 203 is fixedly connected to the side of the magnetic base 201 that contacts the fireplace. The anti-slip rubber pad 203 is slightly lower than the heat-conducting plate 108.

[0039] The heat conduction plate 108 directly contacts the fireplace surface, and the pressure of the elastic connector 3 ensures a tight fit, which effectively improves the heat conduction efficiency. The bimetallic strip 104 temperature sensing element responds sensitively to temperature changes, driving the pointer 1054 to deflect precisely. Together with the clear scale 106, it ensures the accuracy and reliability of temperature readings.

[0040] The elastic connector 3 includes a sliding groove 301 and a connecting rod 302. The sliding groove 301 is formed on the surface of the other side of the magnetic base 201. Several sliding grooves 301 are provided and are distributed circumferentially on the surface of the magnetic base 201. The connecting rod 302 is fixedly connected to the housing 101, and there is a one-to-one correspondence between the connecting rod 302 and the sliding groove 301. The other end of the connecting rod 302 is fixedly connected to a limiting block 303. The limiting block 303 is slidably connected inside the sliding groove 301. A spring 304 is sleeved on the surface of the connecting rod 302. One end of the spring 304 abuts against one end of the sliding groove 301, and the other end of the spring 304 abuts against one side of the limiting block 303.

[0041] With the elastic connector 3 in place, the thermometer body 1 has a certain degree of self-adaptability during use. Even if there is slight unevenness or vibration on the fireplace surface, the spring 304 can continue to provide pressure to ensure good contact between the heat conduction plate 108 and the fireplace surface. At the same time, the anti-slip rubber pad 203 on the magnetic base 201 further increases the stability of the adsorption and prevents sliding and displacement.

[0042] The remaining structure is the same as that in Example 1.

[0043] The workflow of this utility model is as follows:

[0044] First, align the side of the magnetic base 201 of the magnetic assembly 2 with the permanent magnet 202 with the metal surface of the fireplace and fix it with magnetic attraction. With the setting of the magnetic assembly 2, the permanent magnet 202 in the magnetic assembly 2 can make the thermometer body 1 firmly attracted to the metal surface of the fireplace when in use, without the need to drill holes in the fireplace or wall. Installation and disassembly are convenient and quick, avoiding damage to the structural integrity of the fireplace. The anti-slip rubber pad 203 on the magnetic base 201 can increase friction and prevent slippage. At this time, the thermometer body 1 is connected to the magnetic assembly 2 through the elastic connector 3. The heat conduction plate 108 is pressed tightly against the fireplace surface under the pre-pressure of the spring 304 to ensure good thermal contact.

[0045] Secondly, the heat from the fireplace surface is quickly conducted to the interior of the receiving cavity 103 through the heat-conducting plate 108. The bimetallic strip 104 deforms when heated. Since one end is fixed on the fixing pin 1031 and the other end is stuck in the slot 1053 of the pointer assembly 105, the deformation drives the rotating seat 1051 to rotate around the rotating shaft 1032, thereby causing the pointer 1054 to deflect and indicating the corresponding temperature value on the scale 106. The user can clearly read the value through the transparent lens 102. The heat-conducting plate 108 is in direct contact with the fireplace surface, and the pressure of the elastic connector 3 ensures a tight fit, which effectively improves the heat conduction efficiency. The temperature sensing element of the bimetallic strip 104 is sensitive to temperature changes, causing the pointer 1054 to deflect accurately. Combined with the clear scale 106, the accuracy and reliability of the temperature reading are ensured.

[0046] Finally, when it is necessary to disassemble or adjust the position of the thermometer, the user can directly hold the handle 107 with his hand and apply a certain force to overcome the magnetic attraction to remove the thermometer from the fireplace surface. The spring 304 in the elastic connector 3 can adapt to the unevenness of the fireplace surface during disassembly and installation, and always maintain good contact between the heat conduction plate 108 and the fireplace to ensure measurement accuracy.

[0047] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
