[0026] Referring to FIG. 1 and FIG. 2 , an embodiment of the present application provides a constant temperature heating device 100, including a base 10, a shell 20 and a temperature adjustment component 30. The shell 20 is disposed on the base 10. The shell 20 has a mutually independent accommodation chamber 21 and a heating chamber 22. The accommodation chamber 21 is used to accommodate alcohol cotton balls, and the heating chamber 22 is used to accommodate heat exchange medium. The heat exchange medium is used to exchange heat with the accommodation chamber 21 to adjust the temperature of the alcohol cotton balls. Part of the temperature adjustment component 30 is located in the heating chamber 22 and is used to adjust the temperature of the heat exchange medium.

[0027] Specifically, the base 10 can provide support and installation foundation for other structures in the constant temperature heating device 100. The shell 20 is arranged on the base 10, and the shell 20 is hollow inside to form a mutually independent accommodating chamber 21 and heating chamber 22 inside the shell 20, that is, the accommodating chamber 21 and the heating chamber 22 are not connected to each other.

[0028] The accommodating chamber 21 is used to accommodate alcohol cotton balls, and the heating chamber 22 is used to accommodate heat exchange medium. The heat exchange medium can be, but is not limited to, liquid or gas medium, such as water or oil.

[0029] Part of the temperature adjustment component 30 is arranged in the heating chamber 22 to adjust the temperature of the heat exchange medium through the temperature adjustment component 30. In addition, the heating chamber 22 is arranged adjacent to the accommodating chamber 21, and the heat exchange medium in the heating chamber 22 can exchange heat with the accommodating chamber 21, thereby adjusting the temperature of the alcohol cotton ball in the accommodating chamber 21.

[0030] Therefore, through the above structure, the alcohol cotton ball is placed in the accommodating chamber 21, and the temperature of the heat exchange medium is adjusted by the temperature control component 30, so that the temperature in the heating chamber 22 is controlled by the heat exchange medium, and the heat exchange medium in the heating chamber 22 exchanges heat with the accommodating chamber 21, thereby adjusting the temperature of the alcohol cotton ball in the accommodating chamber 21, so that the temperature of the alcohol cotton ball can be maintained within an appropriate range.

[0031] In some embodiments, the heating chamber 22 includes a first sub-chamber 221 and a second sub-chamber 222 that are interconnected. The first sub-chamber 221 penetrates the accommodating chamber 21 , and the second sub-chamber 222 surrounds the outer periphery of the accommodating chamber 21 .

[0032] Specifically, the heating chamber 22 is divided into a first sub-chamber 221 and a second sub-chamber 222, and the first sub-chamber 221 and the second sub-chamber 222 are connected by opening a connecting groove at the bottom. Therefore, when the heat exchange medium is filled into the first sub-chamber 221, the heat exchange medium can flow into the second sub-chamber 222 through the first sub-chamber 221, and the height of the heat exchange medium in the first sub-chamber 221 and the second sub-chamber 222 is kept consistent, so that the heat exchange is more uniform.

[0033] Further, the first sub-cavity 221 is disposed in the accommodating cavity 21, that is, the first sub-cavity 221 is extended in the vertical direction and disposed in the middle position of the accommodating cavity 21. Then, the second sub-cavity 222 is disposed around the outer periphery of the accommodating cavity 21, so that the accommodating cavity 21 forms an annular structure between the first sub-cavity 221 and the second sub-cavity 222.

[0034] Through the above structure, the first sub-cavity 221 and the second sub-cavity 222 can simultaneously exchange heat with the accommodating cavity 21 , and increase the heat exchange area of ​​the accommodating cavity 21 , thereby improving the heat exchange efficiency.

[0035] In some embodiments, a water inlet 23 connected to the first sub-cavity 221 is provided on the shell 20, and the constant temperature heating device 100 also includes a sealing member (not shown in the figure) for sealing the water inlet 23, and the water inlet 23 is used to fill the heat exchange medium into the first sub-cavity 221.

[0036] Specifically, a water inlet 23 is opened at the top of the shell 20, and the water inlet 23 is connected to the first sub-chamber 221. The heat exchange medium can be filled into the first sub-chamber 221 through the water inlet 23. Since the first sub-chamber 221 is connected to the second sub-chamber 222, the heat exchange medium can flow from the first sub-chamber 221 to the second sub-chamber 222, thereby realizing the synchronous filling of the heat exchange medium in the first sub-chamber 221 and the second sub-chamber 222.

[0037] Furthermore, the blocking piece can be used to seal the water inlet 23. The blocking piece can be set as a sealing plug. When there is no need to fill the heat exchange medium, the sealing plug is inserted into the water inlet 23 to achieve the sealing of the water inlet 23, so that a closed space is formed inside the first sub-cavity 221 and the second sub-cavity 222.

[0038] As shown in FIG. 3 , in some embodiments, a liquid level tank 24 communicating with the second sub-cavity 222 is provided on the outer peripheral surface of the shell 20 , and a transparent panel (not shown in the figure) is installed at the water inlet 23 end of the liquid level tank 24 for observing the liquid level height in the liquid level tank 24 .

[0039] The first sub-cavity 221 and the second sub-cavity 222 are interconnected, and the liquid level tank 24 is interconnected with the second sub-cavity 222, so that the first sub-cavity 221, the second sub-cavity 222 and the liquid level tank 24 are interconnected, and the liquid levels in the first sub-cavity 221, the second sub-cavity 222 and the liquid level tank 24 are consistent. Furthermore, a transparent panel is installed at the water inlet 23 end of the liquid level tank 24, through which the liquid level in the liquid level tank 24 can be quickly and clearly observed, so that the liquid level in the first sub-cavity 221 and the second sub-cavity 222 can be quickly known.

[0040] In some embodiments, the temperature control assembly 30 includes a controller 31 and a heating pipe 32 that are connected to each other. The controller 31 is disposed on the base 10 , and at least a portion of the heating pipe 32 extends into the first sub-cavity 221 and the second sub-cavity 222 , respectively.

[0041] Specifically, the controller 31 can be configured as a constant temperature heater, and the heating pipe 32 can be configured as a heating copper pipe. The constant temperature heater is connected to the heating copper pipe and can be used to adjust the temperature of the heating copper pipe.

[0042] The heating copper tube can be divided into a first branch tube and a second branch tube, the first branch tube and the second branch tube are respectively connected to the constant temperature heater, and the first branch tube extends into the first sub-cavity 221, and the second branch tube extends into the second sub-cavity 222.

[0043] Thus, the constant temperature heater adjusts the temperature of the first branch pipe and the second branch pipe, and then the first branch pipe heats the heat exchange medium in the first sub-cavity 221, and the second branch pipe heats the heat exchange medium in the second sub-cavity 222, so that the heat exchange medium in the first sub-cavity 221 and the second sub-cavity 222 can exchange heat with the accommodating cavity 21.

[0044] Furthermore, in order to reasonably utilize the space, a storage groove may be opened below the base 10 , and the heating copper tube may be stored in the storage groove, thereby reducing the overall volume of the constant temperature heating device 100 .

[0045] In some embodiments, the temperature adjustment component 30 further includes a temperature detection component 33 disposed on the housing 20 , and the temperature detection component 33 is used to detect the temperature in the second sub-cavity 222 .

[0046] Since the first sub-cavity 221 is connected to the second sub-cavity 222, the temperature in the first sub-cavity 221 is consistent with that in the second sub-cavity 222. The temperature in the second sub-cavity 222 is detected by the temperature detection member 33, which can reflect the temperature in the first sub-cavity 221, thereby better controlling the temperature of the first sub-cavity 221 and the second sub-cavity 222.

[0047] In some embodiments, the constant temperature heating device 100 further includes a heat preservation sleeve (not shown) disposed around the outer periphery of the shell 20. The heat preservation sleeve can insulate the internal accommodation cavity 21 and the heating cavity 22 of the shell 20 to better regulate the temperature.

[0048] In some embodiments, the accommodating cavity 21 is constructed as an annular cavity, and the constant temperature heating device 100 also includes a tray 40 and a driving assembly 50 connected to the accommodating cavity. The driving assembly 50 is arranged on the base 10, and the tray 40 is arranged in the accommodating cavity 21 for carrying alcohol cotton balls, and is configured to be able to rotate around the axial direction of the accommodating cavity 21 under the drive of the driving assembly 50.

[0049] The accommodating chamber 21 is an annular cavity. The tray 40 is arranged in the accommodating chamber 21, and the alcohol cotton balls are placed on the tray 40. The driving component 50 can drive the tray 40 to rotate around the axial direction of the accommodating chamber 21, thereby driving the alcohol cotton balls placed thereon to rotate.

[0050] Therefore, in the process of exchanging heat with the alcohol cotton balls in the accommodating chamber 21 through the heating chamber 22, the tray 40 drives the alcohol cotton balls to rotate, which can make the alcohol cotton balls heated more evenly and improve the heat exchange efficiency.

[0051] In some embodiments, the driving assembly 50 includes a driving motor 51 and a transmission gear 52 that are drive-connected. The driving motor 51 is disposed on the base 10. An inner gear ring 41 meshing with the transmission gear 52 is disposed at the bottom of the tray 40. The transmission gear 52 is configured to be able to rotate relative to the inner gear ring 41 under the drive of the driving motor 51 to drive the tray 40 to rotate.

[0052] Specifically, the driving motor 51 is disposed in the receiving groove of the base 10, one end of the transmission gear 52 is drivingly connected to the driving motor 51, and the other end is meshed with the inner gear ring 41 at the bottom of the tray 40. After the driving motor 51 is turned on, the transmission gear 52 is driven to rotate, thereby driving the inner gear ring 41 to rotate through the transmission gear 52, thereby driving the tray 40 to rotate.

[0053] In some embodiments, the housing 20 includes a body 25 and a cover 26 . The cover 26 seals and covers the opening of the body 25 , and together with the body 25 , forms a receiving cavity 21 .

[0054] Specifically, the body 25 is provided with an opening, through which the alcohol cotton ball can be placed into the accommodating chamber 21. Further, the opening is sealed and covered by the cover 26, so that a closed environment is formed in the accommodating chamber 21.

[0055] According to one or more embodiments, firstly, an alcohol cotton ball is placed in the receiving chamber 21 and placed on the tray 40. The cover 26 is sealed to cover the opening of the body 25, so that the receiving chamber 21 forms a closed environment.

[0056] A heat exchange medium is added into the first sub-cavity 221, and the heat exchange medium flows into the second sub-cavity 222 and the liquid level tank 24 through the first sub-cavity 221. The constant temperature heater is turned on to heat the heat exchange medium in the first sub-cavity 221 and the second sub-cavity 222 through the heat exchange pipe, so that heat is exchanged with the accommodating cavity 21 through the heat exchange medium.

[0057] At the same time, the driving motor 51 is turned on, and the inner gear ring 41 meshing with the transmission gear 52 is driven to rotate, thereby driving the tray 40 to rotate, so that the alcohol cotton ball placed thereon rotates accordingly, thereby improving the uniformity of the heat exchange process.

[0058] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0059] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
