[0058] In some examples, the oil tank body 200 is a closed shell 103 , and the partition wall 2034 is directly formed in the oil tank body 200 , separating the installation cavity 59 and the oil supply cavity 52 in the oil tank body 200 .

[0059] In other instances, see Figure 8-9 The oil tank body 200 includes a shell 201 and a mounting seat 203. One end of the shell 201 is open. The mounting seat 203 is installed in the opening of the shell 201 through a sealing rubber ring 202, wherein a snap-fit ​​structure can also be provided between the mounting seat 203 and the shell 201. The shell 201 has a recess C1 at the end of the opening, the mounting cavity 59 is formed in the mounting seat 203, the first oil-passing portion 54 is provided at a position corresponding to the recess C1 on the mounting seat 203, the side wall of the mounting seat 203 facing the oil supply cavity 52 serves as the partition wall 2034, and the second oil-passing portion 55 is provided on the side wall of the mounting seat 203. In this example, the first oil-passing portion 54 and the second oil-passing portion 55 are through holes 3021 provided on the mounting seat 203.

[0060] The mounting seat 203 is provided with a first through hole 2033, and the valve component 301 is inserted into the mounting cavity 59 through the first through hole 2033. The housing 201 is also provided with a second through hole 201a corresponding to the first through hole 2033.

[0061] The activity of the valve component 301 includes but is not limited to at least one of movement and rotation. Movement here refers to movement along a certain track, and rotation refers to rotation around its own axis.

[0062] See also Figure 11-13In some examples, the valve component 301 is rotatably installed in the installation cavity 59 and rotates between the first rotation position A1 and the first rotation position A2. The valve component 301 is provided with an oil delivery portion 3011 for connecting the first oil passage portion 54 and the second oil passage portion 55. The first rotation position A1 is a position where the oil delivery portion 3011 is connected to the first oil passage portion 54 and the second oil passage portion 55, respectively, and then connects the first oil passage portion 54 and the second oil passage portion 55. The first rotation position A2 is a position where the valve component 301 blocks the first oil passage portion 54 and / or the second oil passage portion 55. The oil delivery portion 3011 includes but is not limited to a hole, a groove, etc. For example, a through hole or a groove is provided on the valve component 301. In this example, the oil delivery part 3011 is a groove provided on the valve component 301. When the valve component 301 rotates to the first rotation position A1, the groove corresponds to the first oil passage part 54 and the second oil passage part 55 at the same time. The smoke oil is discharged from the oil supply chamber 52 through the second oil passage part 55, the oil delivery part 3011, and the first oil passage part 54 in sequence. The oil delivery part 3011 serves as a transmission channel. When the valve component 301 rotates to the first rotation position A2, the groove turns to the other side. At this time, the valve component 301 itself blocks the first oil passage part 54, or the valve component 301 itself blocks the second oil passage part 55, or blocks the first oil passage part 54 and the second oil passage part 55 at the same time. When a through hole is provided on the valve component 301, the positions of the first oil passage part 54 and the second oil passage part 55 should be relative positions, and then the two are connected or blocked through the through hole.

[0063] Among them, see Fig.10, a driving component 301 for driving the valve component 301 to move is provided at one end of the valve component 301, and the driving component 301 is at least partially exposed outside the oil tank body 200, so that the user can use the driving component 301 to drive the valve component 301 to move. In some embodiments, the driving component 301 is provided with a "one"-shaped or "cross"-shaped twisting portion 3032, which is convenient for user operation. Among them, the valve component 301 is roughly rod-shaped, and the driving component 301 and the valve component 301 are fixed to each other. In this example, the valve component 301 and the driving component 301 are respectively provided with a limiting groove 3012 and a positioning rod 3031 adapted to the limiting groove 3012 on the opposite sides, wherein the limiting groove is roughly in the shape of a four-petal petal, wherein the length of the two opposite lobes is greater than the length of the other two opposite lobes. The driving component 301 is assembled with the valve component 301 through the limiting groove 3012 and the positioning rod 3031 to ensure consistency during the production and assembly process, thereby ensuring that the exposed twisting portion 3032 can clearly indicate the position of the valve component 301. For example, during production and assembly, the extension direction of the "I"-shaped twisting portion 3032 is made to correspond to the relatively longer two relatively long petals on the positioning rod 3031. When the driving component 301 is assembled with the positioning rod 3031 and the limiting groove 3012, it can be ensured that when the "I"-shaped twisting portion 3032 is horizontal, the valve component 301 is in the first rotation position A2, and when the "I"-shaped twisting portion 3032 tends to be vertical, the valve component 301 is in the first rotation position A1.

[0064] Among them, see Fig.11 The valve component 301 is limited to the first rotation position A1 and the first rotation position A2 by the sliding protrusion 2034 and the circumferential slideway 3014. One of the sliding protrusion 2034 and the circumferential slideway 3014 is arranged on the valve component 301, and the other of the sliding protrusion 2034 and the circumferential slideway 3014 is arranged in the installation cavity 59, that is, arranged on the wall of the installation seat 203. Taking an example, a circumferential slideway 3014 is formed on the circumference of one end of the valve component 301, and the inner wall of the installation seat 203 is provided with a sliding protrusion 2034. When the valve component 301 is rotated, the sliding protrusion 2034 slides relatively with the circumferential slideway 3014, and the rotation stroke of the valve component 301 is limited by the circumferential slideway 3014.

[0065] Among them, see Fig.10The outer periphery of the valve component 301 is also covered with a sealing rubber sleeve 302, and the sealing rubber sleeve 302 is provided with a through hole 3021 communicating with the oil delivery part 3011. The outer periphery of the sealing rubber sleeve 302 is also protruded to form a sealing ring body 3022 for sealing the first oil passing part 54 and / or the second oil passing part 55, which plays a sealing role, and then plays a role of complete blocking to prevent oil leakage. Among them, the valve component 301, the driving component 301, and the sealing rubber sleeve 302 are collectively used as the valve assembly 300.

[0066] See also Figure 14-15 In other examples, the outer circumference of the valve component 301 is provided with an external thread 301a, and the wall of the mounting seat 203 corresponding to the mounting cavity 59 is provided with an internal thread 301b, and the mounting cavity 59 itself serves as an oil delivery portion 3011. As the valve component 301 is rotated, the valve component 301 moves outward, so that the first oil passage portion 54 and the second oil passage portion 55 are communicated through the mounting cavity 59. As the valve component 301 is rotated in the opposite direction, the valve component 301 moves inward, and then one end of the valve component 301 blocks the first oil passage portion 54 and / or the second oil passage portion 55. In other examples, the valve component 301 may not adopt a rotating movable mode, but directly move out of or into the mounting cavity 59 along a straight line.
