Description

Technical Field

[0001] This utility model relates to the field of heating, and in particular to an alcohol fireplace structure. Background Technology

[0002] Currently, alcohol fireplaces are heating devices that provide warmth to indoor spaces. They generate heat by burning alcohol and have seen rapid development due to their advantages of being smokeless, odorless, environmentally friendly, and emission-free.

[0003] In existing alcohol fireplaces, such as the technical solution disclosed in Chinese patent literature with patent application number 202211228232.3 entitled "An Adjustable Automatic Alcohol Fireplace with Higher Safety and More Complete Flame Combustion," this solution mainly includes a fireplace metal box, within which are arranged sequentially an alcohol storage tank, a liquid level balance tank, and an alcohol evaporation tank. The top of the fireplace metal box has a combustion groove with an ignition rod, and the combustion groove is connected to the alcohol evaporation tank. The alcohol level in the liquid level balance tank is always balanced with the alcohol level in the alcohol evaporation tank. In use, the alcohol in the storage tank flows through the liquid level balance tank and then to the alcohol evaporation tank, where it is heated into vaporized alcohol. Finally, the vaporized alcohol is conducted to the combustion groove and ignited by the ignition rod. Although this combustion method of heating and evaporating liquid alcohol into gas allows the gaseous alcohol to fully contact the air and burn completely, greatly reducing the problem of strong alcohol odor caused by incomplete combustion, this solution still has the following shortcomings in practical applications:

[0004] Because alcohol heating only takes place in the alcohol evaporation tank, while the alcohol in the storage tank and level balance tank is at a constant low temperature, during combustion, when the alcohol in the evaporation tank is insufficient, adding low-temperature alcohol will cause the temperature of the high-temperature alcohol in the evaporation tank to drop rapidly due to the temperature difference. This will lead to a rapid decrease in the produced gaseous alcohol, a drop in flame height, and then a long heating time is required for the liquid alcohol in the evaporation tank to return to a high temperature before the flame height rises again. This results in unstable flame height, causing the heating temperature to fluctuate, significantly impacting the user experience.

[0005] Therefore, given the aforementioned shortcomings of existing alcohol fireplaces, it is essential to further improve their structure in order to better meet people's application needs. Utility Model Content

[0006] The purpose of this utility model is to solve the above-mentioned problems and deficiencies and provide an alcohol fireplace structure. This alcohol fireplace structure, by setting a preheating box device, allows the low-temperature alcohol in the storage tank to be preheated in the preheating box device before flowing to the high-temperature vaporization box device. The preheated alcohol is then transported to the high-temperature vaporization box device, which greatly reduces the temperature difference, maintains the amount of gaseous alcohol produced, and keeps the flame height stable, thereby ensuring a stable heating temperature and a better user experience.

[0007] The technical solution of this utility model is implemented as follows: an alcohol fireplace structure includes a shell, a liquid storage tank and a high-temperature vaporization chamber device disposed within the shell, and a combustion chamber device connected to the high-temperature vaporization chamber device on the shell. The feature is that it also includes a preheating chamber device disposed within the shell. The liquid storage tank, the preheating chamber device and the high-temperature vaporization chamber device are connected in sequence, and the heating temperature of the preheating chamber device is lower than or equal to the heating temperature of the high-temperature vaporization chamber device.

[0008] Preferably, an alcohol recovery pipeline is provided between the preheating box device and the storage tank, and an alcohol return pump is connected to the alcohol recovery pipeline.

[0009] Preferably, the preheating chamber device is provided with a preheating inner cavity connected to the alcohol recovery pipeline, and the high-temperature vaporization chamber device is provided with a high-temperature vaporization inner cavity connected to the preheating inner cavity, and the bottom of the high-temperature vaporization inner cavity is higher than the bottom of the preheating inner cavity.

[0010] Preferably, the preheating chamber device includes a preheating chamber body and a preheating plate disposed on the outer wall of the preheating chamber body, and the preheating inner cavity is disposed in the preheating chamber body; the preheating inner cavity is also provided with a liquid level sensor.

[0011] Preferably, the high-temperature vaporization chamber device includes a high-temperature vaporization chamber body and a high-temperature heating plate disposed on the outer wall of the high-temperature vaporization chamber body, and the high-temperature vaporization inner cavity is disposed in the high-temperature vaporization chamber body.

[0012] Preferably, the high-temperature vaporization box device further includes a clamping component, and the high-temperature heating plate and the high-temperature vaporization box body are clamped together by the clamping component.

[0013] Preferably, there are two high-temperature heating plates, one of which is disposed on the bottom surface of the high-temperature gasification chamber and the other is disposed on the outer side wall of the high-temperature gasification chamber.

[0014] Preferably, the combustion chamber device includes a combustion chamber body and an igniter connected to the high-temperature gasification chamber device. The top surface of the combustion chamber body is provided with a plurality of flame ejection holes that penetrate into its interior. The igniter penetrates from the bottom to the top of the combustion chamber body, and the ignition end of the igniter is located outside the flame ejection holes. A sealing sleeve is also provided between the igniter and the combustion chamber body.

[0015] Preferably, the present invention further includes a cooling fan disposed inside the housing, and the housing is provided with an air inlet and an air outlet communicating with the interior thereon; the top of the housing is provided with an opening for the combustion chamber device to extend out, and the air outlet is formed between the opening and the combustion chamber device.

[0016] Preferably, the present invention further includes a control circuit board disposed inside the housing and an operation panel disposed on the top surface of the housing, wherein the operation panel, the preheating box device, the high-temperature gasification box device, and the combustion box device are electrically connected to the control circuit board.

[0017] The beneficial effects of this utility model are as follows: By setting up a preheating box device, the low-temperature alcohol in the storage tank is preheated in the preheating box device before flowing into the high-temperature vaporization box device. The preheated alcohol is then transported to the high-temperature vaporization box device, which greatly reduces the temperature difference and shortens the heating time of the high-temperature vaporization box device. This results in very small temperature changes of the high-temperature alcohol in the high-temperature vaporization box device, maintaining the amount of gaseous alcohol produced and ensuring that the flame height remains stable without jumping up and down. This, in turn, ensures a stable heating temperature and greatly enhances the user's experience. Attached Figure Description

[0027] like Figure 1 and Figure 2 As shown, the present invention discloses an alcohol fireplace structure comprising a shell 1, a liquid storage tank 2 disposed within the shell 1, and a high-temperature vaporization chamber device 3. The shell 1 also includes a combustion chamber device 5 connected to the high-temperature vaporization chamber device 3. To achieve the objectives of this invention, a preheating chamber device 4 disposed within the shell 1 is further included. The liquid storage tank 2, the preheating chamber device 4, and the high-temperature vaporization chamber device 3 are sequentially connected, and the heating temperature of the preheating chamber device 4 is lower than or equal to the heating temperature of the high-temperature vaporization chamber device 3. By incorporating the preheating chamber device 4, the low-temperature alcohol in the liquid storage tank 2 is preheated in the preheating chamber device 4 before flowing to the high-temperature vaporization chamber device 3. This significantly reduces the temperature difference, maintaining the amount of gaseous alcohol produced, ensuring a stable flame height, and thus guaranteeing a stable heating temperature and a superior user experience.

[0028] In practical applications, since the boiling point of alcohol is 78.3 degrees Celsius, this invention provides two implementation schemes: First, the heating temperature of the preheating chamber device 4 is equal to the heating temperature of the high-temperature vaporization chamber device 3, and both have the same heating power. Second, the heating temperature of the preheating chamber device 4 is lower than the heating temperature of the high-temperature vaporization chamber device 3. The preheating chamber device 4 serves as the heating component for heating liquid alcohol to 60-70 degrees Celsius, while the high-temperature vaporization chamber device 3 serves as the heating component for heating liquid alcohol to 78.3 degrees Celsius. Preferably, this invention adopts the second scheme, which allows the liquid alcohol to undergo substantial vaporization in the high-temperature vaporization chamber device 3, preventing the generation of large amounts of gaseous alcohol in the preheating chamber device 4, thus optimizing energy use, avoiding ineffective power consumption, and reducing electricity waste.

[0029] In practical applications, the liquid storage tank 2, the preheating box device 4, and the high-temperature vaporization box device 3 are connected together via a pipe equipped with a solenoid valve.

[0030] To ensure the flame is extinguished quickly when the alcohol fireplace is turned off, such as... Figure 2As shown, an alcohol recovery pipe 6 is also provided between the preheating box device 4 and the storage tank 2, and an alcohol return pump 60 is connected to the alcohol recovery pipe 6. Since the high-temperature vaporization box device 3 and the preheating box device 4 are connected, when shutting down, the alcohol in the high-temperature vaporization box device 3 and the preheating box device 4 can be returned to the storage tank 2 simply by using the alcohol recovery pipe 6 and the alcohol return pump 60. There is no need to wait for the alcohol in the high-temperature vaporization box device 3 to burn out, the flame extinguishes faster, there is no waste of alcohol fuel, and the safety is also high.

[0031] In order to extinguish the flame more quickly, such as Figure 3 As shown, the preheating chamber device 4 is provided with a preheating inner cavity 40 connected to the alcohol recovery pipe 6, and the high-temperature vaporization chamber device 3 is provided with a high-temperature vaporization inner cavity 30 connected to the preheating inner cavity 40, with the bottom of the high-temperature vaporization inner cavity 30 being higher than the bottom of the preheating inner cavity 40. This allows the high-temperature vaporization inner cavity 30 to empty the liquid alcohol earlier than the preheating inner cavity 40, thus enabling the flame to extinguish more quickly. Specifically, the bottom edge of the liquid inlet and outlet of the high-temperature vaporization chamber device 3 is flush with the bottom of the high-temperature vaporization inner cavity 30, ensuring that the alcohol in the high-temperature vaporization inner cavity 30 can be quickly emptied.

[0032] To further improve the structure of the preheating box device 4, such as Figure 2 and Figure 3 As shown, the preheating chamber device 4 includes a preheating chamber body 41 and a preheating plate 42 disposed on the outer wall of the preheating chamber body 41, and the preheating inner cavity 40 is disposed in the preheating chamber body 41. This makes the structure of the preheating chamber device 4 simpler and easier to manufacture.

[0033] To prevent dry burning in the preheated cavity 40, such as Figure 3 As shown, a liquid level sensor 43 is also provided in the preheating cavity 40.

[0034] To further improve the structure of the high-temperature vaporization box device 3, such as Figure 6 and Figure 7 As shown, the high-temperature vaporization chamber device 3 includes a high-temperature vaporization chamber body 31 and a high-temperature heating plate 32 disposed on the outer wall of the high-temperature vaporization chamber body 31, and the high-temperature vaporization inner cavity 30 is disposed in the high-temperature vaporization chamber body 31. This makes the structure of the high-temperature vaporization chamber device 3 simpler and easier to manufacture.

[0035] In order to ensure that the high-temperature heating plate 32 can be tightly installed on the high-temperature vaporization chamber 31, such as Figure 6As shown, the high-temperature vaporization chamber device 3 also includes a clamping member 33, which clamps the high-temperature heating plate 32 and the high-temperature vaporization chamber body 31 together. In practical applications, the clamping member 33 adopts a commonly used ring-shaped clamping member available on the market. It can be a ring-shaped clamping member tightened by screws or a wire that is manually wrapped and tied.

[0036] In order to heat and vaporize the liquid alcohol in the high-temperature vaporization chamber device 3 more quickly, such as Figure 7 As shown, there are two high-temperature heating plates 32, one of which is located on the bottom surface of the high-temperature gasification chamber 31, and the other is located on the outer wall of the high-temperature gasification chamber 31.

[0037] To further improve the structure of the combustion chamber device 5, such as Figure 7 and Figure 8 As shown, the combustion chamber device 5 includes a combustion chamber body 51 connected to the high-temperature vaporization chamber device 3 and an igniter 52. The top surface of the combustion chamber body 51 has several flame outlet holes 53 extending into it. The igniter 52 extends from the bottom to the top of the combustion chamber body 51, with its ignition end located outside the flame outlet holes 53. Specifically, the combustion chamber body 51 is connected to the high-temperature vaporization chamber 30. By extending the igniter 52 from the bottom to the top of the combustion chamber body 51, only its ignition end is exposed, resulting in a simpler overall design for the alcohol fireplace. Furthermore, the ignition end being located outside the flame outlet holes 53 allows the ignition operation to be completed outside the alcohol fireplace, making it safer to use.

[0038] In actual use, in order to ensure that all the gaseous alcohol produced after the machine is turned off and to ensure safety, the igniter is turned on again during the process of drawing alcohol from the alcohol recovery pipe 6, so as to fully burn off the gaseous alcohol inside and outside the combustion chamber 51, which makes the use safer.

[0039] To improve sealing and prevent the flame from burning inwards after ignition, such as Figure 7 As shown, a sealing sleeve 54 is also provided between the igniter 52 and the combustion chamber 51.

[0040] To cool the electrical components inside the alcohol fireplace and extend their lifespan, such as... Figure 2 and Figure 5 As shown, the present invention also includes a cooling fan 7 disposed inside the housing 1, and the housing 1 is also provided with an air inlet 11 and an air outlet 12 communicating with its interior.

[0041] To further refine the specific placement of air outlet 12, such as Figure 5As shown, the top of the housing 1 is provided with an opening 13 for the combustion chamber device 5 to extend out, and the air outlet 12 is formed between the opening 13 and the combustion chamber device 5. This allows the output air to be arranged around the combustion chamber device 5 and blown vertically upward, which on the one hand helps combustion, and on the other hand prevents the flame from spreading around, making it safer to use and improving the flame output effect.

[0042] To facilitate observation and control of the operation of various electrical components, such as Figure 2 and Figure 9 As shown, this utility model also includes a control circuit board 8 disposed inside the housing 1 and an operation panel 9 disposed on the top surface of the housing 1. The operation panel 9, the preheating plate 42 and liquid level sensor 43 of the preheating box device 4, the high temperature heating plate 32 of the high temperature vaporization box device 3, the igniter 52 of the combustion box device 5, the alcohol return pump 60, and the cooling fan 7 are electrically connected to the control circuit board 8.

[0043] To prevent the high-temperature flame from burning the control panel 9, such as Figure 9 As shown, the housing 1 is also provided with a cover plate 10 to cover the control panel 9. Specifically, the cover plate 10 can be connected to the housing 1 by means of a cover or hinge. The housing 1 is also provided with a push-to-open mechanism 103 that acts on the cover plate 10 to achieve the purpose of opening and closing the cover plate 10. The push-to-open mechanism 103 is a common push-to-open component used in concealed cabinet doors, and its specific structure will not be described in detail here.

[0044] To more easily measure the remaining alcohol level in storage tank 2, such as... Figure 4 As shown, the liquid storage tank 2 is equipped with a level gauge 21 that is electrically connected to the control circuit board 8. This allows for convenient observation of the liquid level in the liquid storage tank 2 via the control panel 9.

[0045] In practical applications, in order to more conveniently observe the heating temperature of the preheating box device 4, the high-temperature gasification box device 3, and the combustion temperature of the combustion box device 5, the preheating box device 4, the high-temperature gasification box device 3, and the combustion box device 5 are respectively equipped with thermometers that are electrically connected to the control circuit board 8.

[0046] In practical applications, to facilitate adding and removing liquid from storage tank 2, such as... Figure 4 As shown, the housing 1 is also provided with an inlet pipe 101 and a drain pipe 102 with a battery valve 100 inside. One end of the inlet pipe 101 and the drain pipe 102 are respectively connected to the storage tank 2, and the other end of the inlet pipe 101 and the drain pipe 102 are respectively provided on the top surface of the housing 1.

[0047] In practical applications, to prevent a vacuum inside the liquid storage tank 2, such as Figure 4As shown, the liquid storage tank 2 is also equipped with an exhaust pipe 22. This prevents the addition and extraction of liquid from being affected.
