Therefore, the above terms should not be understood as limiting the present invention.

[0023] It is to be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the element may be multiple, and the term "one" should not be understood as a limitation on the quantity.

[0024] like Figure 1-4 The utility model provides a constant temperature oil bath device, including an oil bath pot 1, a detachable inner pot 2 placed inside the oil bath pot 1, an oil bath cavity 3 is opened inside the inner pot 2, a fixed pile 4 is provided at the bottom of the oil bath cavity 3, a stirring rod 5 is rotatably mounted on the fixed pile 4, and a plurality of stirring blades 6 are distributed at intervals along the circumference of the stirring rod 5.

[0025] When the object is heated in an oil bath, the object is placed in the oil bath cavity, and sufficient oil is added to the oil bath cavity so that the oil submerges the object, and then the oil is heated by the heating element built into the oil bath pot to ensure stable oil bath heating of the object. During the heating process, the stirring rod can be rotated relative to the fixed pile so that the stirring rod drives a number of stirring blades to stir the oil, thereby increasing the heating efficiency and ensuring that the heating degree of various parts of the object is relatively uniform. When the oil bath cavity needs to be cleaned, the inner liner can be disassembled from the oil bath pot, and then the inner liner can be cleaned directly without moving the entire equipment, which greatly improves the convenience of the cleaning process.

[0026] Among them, the selection of heating elements in the oil bath pot is consistent with the heating elements of the existing oil bath pot, and will not be described in detail here.

[0027] In a preferred embodiment of the present scheme, an oil seal is provided at the rotation connection between the fixed pile and the stirring rod to form a dynamic seal, so that when the stirring rod rotates relative to the fixed pile, oil will not leak into the inside of the stirring rod.

[0028] Preferably, a driving mechanism is connected to the bottom of the oil bath pot 1, and the driving mechanism includes a mounting seat 7 connected to the bottom of the oil bath pot 1, and a first driving wheel 8 rotatably connected to the mounting seat 7, and the first driving wheel 8 is in transmission cooperation with the stirring rod 5 through a transmission rod 9, and the transmission rod 9 passes through the bottom of the oil bath pot 1 and the fixed pile 4.

[0029] Specifically, when the inner pot is installed on the oil bath, the transmission rod is passed through and connected to the stirring rod, so that the first driving wheel and the stirring rod are connected through the transmission rod. Then, after the items and oil are placed in the inner pot, the first driving wheel is rotated, so that the transmission rod drives the stirring rod to rotate, thereby ensuring the stirring and heating effect of the oil.

[0030] Preferably, a plurality of positioning grooves 10 are provided on the inner side of the stirring rod 5 , a plurality of positioning rods 11 matching the positioning grooves 10 are provided on the end of the transmission rod 9 , and the transmission rod 9 and the stirring rod 5 are detachably matched.

[0031] Specifically, when the transmission rod is connected to the stirring rod, the positioning rod is inserted into the positioning groove, so that the stirring rod can be driven to rotate when the transmission rod rotates, and the transmission rod and the stirring rod are detachably matched.

[0032] Preferably, a plurality of contraction grooves 12 are formed at the end of the transmission rod 9 , the positioning rod 11 is movably installed in the contraction groove 12 , and an elastic member 13 is connected between the positioning rod 11 and the contraction groove 12 .

[0033] Specifically, when the transmission rod and the stirring rod are connected, the positioning rod may not be able to be accurately inserted into the positioning groove. Therefore, when the positioning rod and the positioning groove are not successfully matched, the positioning rod is blocked by the stirring rod, causing the positioning rod to shrink into the shrinkage groove. Subsequently, when the first driving wheel drives the transmission rod to rotate, the positioning rod moves to the position of the positioning groove. At this time, the elastic member pushes the positioning rod to pop out, so as to ensure that the positioning rod can be inserted into the positioning groove, thereby completing the connection between the transmission rod and the stirring rod.

[0034] The elastic member may be a spring structure.

[0035] Preferably, a guide groove 14 is provided at the opening of the positioning groove 10 along the circumferential direction.

[0036] Specifically, by providing the guide groove, the end of the positioning rod is guided, so that the positioning rod can enter the positioning groove more easily, thereby improving the matching effect between the positioning rod and the positioning groove.

[0037] Preferably, the oil drain pipe runs through the bottom of the mounting seat 7 to an end of the transmission rod 9 close to the stirring rod 5 .

[0038] Specifically, after the oil seal between the fixed pile and the stirring rod has been used for a long time, the oil seal may fail. At this time, the lubricating oil in the oil seal or the oil in the oil bath cavity may enter the connection between the stirring rod and the transmission rod. In order to prevent the oil from leaking into the mounting seat, an oil drain pipe is provided in this scheme. When the oil enters the connection between the stirring rod and the transmission rod, the oil will flow along the oil drain pipe, and then the oil will be guided and discharged to the outside of the bottom of the mounting seat through the oil drain pipe, so as to avoid the accumulation of oil at the mounting seat.

[0039] Preferably, a second driving wheel 15 is rotatably provided on the mounting seat 7 , the second driving wheel 15 is controlled to rotate by a driving member 16 , and the first driving wheel 8 and the second driving wheel 15 are meshed with each other.

[0040] Specifically, the second driving wheel is controlled to rotate by the driving member, and then the first driving wheel is controlled to rotate by the second driving wheel to ensure the stirring effect.

[0041] The driving part can be a motor in combination with a reducer.

[0042] Preferably, a plurality of gaskets 17 are distributed at intervals along the circumferential direction on the inner bottom of the oil bath pot 1 , and when the inner pot 2 is placed inside the oil bath pot 1 , the bottom of the inner pot 2 is placed on the plurality of gaskets 17 .

[0043] Specifically, when the inner pot is placed in the oil bath, the bottom of the inner pot is supported by the gasket, so as to improve the placement stability of the inner pot and reduce the collision between the inner pot and the oil bath.

[0044] Among them, the gasket can be a rubber pad.

[0045] Preferably, handles 18 are provided on opposite sides of the inner liner 2 .

[0046] Specifically, when the inner pot needs to be taken out from the oil bath, the inner pot can be lifted by pulling the handle to facilitate taking out the inner pot.

[0047] Preferably, a plurality of snap-in grooves 19 are circumferentially formed on the inner side of the oil bath chamber 3 , and a storage rack 20 is disposed inside the oil bath chamber 3 . The sides of the storage rack 20 are connected to the snap-in grooves 19 via a clamping plate 21 , and the storage rack 20 is disposed higher than the stirring rod 5 .

[0048] Specifically, when placing items in the oil bath cavity, the rack is first placed in the oil bath cavity, and the sides of the rack are positioned and supported by the cooperation of the clamping plate and the clamping groove to ensure the stability of the items when placed on the rack. Since the rack is positioned by the clamping plate and the clamping groove, the rack can be easily taken out of the oil bath cavity to facilitate the cleaning of the bottom of the oil bath cavity and the rack.

[0049] The present utility model is not limited to the above-mentioned optimal implementation mode. Anyone can derive other various forms of products under the inspiration of the present utility model. However, no matter what changes are made in the shape or structure, all those having the same or similar technical solutions as the present application fall within the protection scope of the present utility model.
