In addition, the diameters of the first tube body 111 and the second tube body 122 are the same, so that the dimensions of the shaft 1 are approximately the same from top to bottom. As a whole, the shaft 1 is generally in the shape of a rod, which makes the steam mop more flexible and easy to use.

Optionally, the ratio of the radial dimension to the axial dimension of the shaft 1 may be 0.01-0.3, for example, may be 0.01, 0.012, 0.015, 0.017, 0.02, 0.022, 0.025, 0.027, 0.03, etc. an enumeration. Within this range, the length of the shaft 1 is much larger than the radial width, which makes the use of the steam mop more light and flexible. Exemplarily, the overall length of the shaft 1 may be 1000mm-1200mm, such as 1050mm, 1100mm, 1150mm, 1200mm. The radial dimension of the shaft 1 may be 15mm-30mm, such as 15mm, 20mm, 25mm, 30mm, etc., which will not be listed one by one here.

Further, the projection of the pallet 3 along the axial direction of the shaft 1 deviates from the projection of the shaft 1 . As a result, the steam engine 200 is deviated from the shaft 1 as a whole, and is supported by the bracket 3, there is no need to construct a structure for accommodating the steam engine 200 on the shaft 1, and the shaft 1 can also be kept as a straight rod, which makes the structure of the steam mop more convenient. Simple and lightweight. Among them, more than 80% of the projection of the pallet 3 along the axial direction of the shaft 1 deviates from the projection of the shaft 1 along the axial direction thereof. Optionally, when the steam engine 200 is placed on the pallet 3 , the body of the steam engine 200 is at least partially spaced apart from the shaft 1 along the radial direction of the shaft 1 . In a specific embodiment, 90%-95% of the body is spaced from the shaft 1 along the length of the shaft 1 . With this structure, in addition to disposing the pallet 3 supporting the steam engine 200 on the shaft 1, there is no need to construct a structure matching the steam engine 200 on the shaft 1, which further simplifies the structure of the shaft 1 and the entire steam mop The structure of the steam mop makes the structure of the steam mop more concise, the use more flexible, and the manufacturing cost is also lower.

In this embodiment, the steam engine 200 is detachably placed on the pallet 3, which can facilitate the user to select the working mode of the steam mop according to their needs, that is, choose to use the steam engine 200 alone, use the floor mop mechanism 100 alone, the steam engine 200 and the floor mop mechanism. 100 used in combination. Thus, the use range of the steam mop is expanded.

In order to further improve the stability of the steam engine 200 , the lower end of the steam engine 200 is placed on the pallet 3 , and the upper end of the steam engine 200 is connected to the shaft 1 . By fixing the upper and lower ends of the steam engine 200 , the fixing effect of the steam engine 200 can be made more stable on the basis of simplifying the fixing structure of the steam engine 200 .

Specifically, as shown in FIGS. 2 and 3 , the pallet 3 is connected to the floor brush assembly 2 or the lower end of the shaft 1 , so that after the steam engine 200 is installed on the pallet 3 , the overall center of gravity of the steam mop is lower, which is convenient for users to adjust The posture of the steam mop makes the use of the steam mop more light and flexible.

In addition, the platform 3 is arranged on the floor brush assembly 2 or the lower end of the shaft 1, so that the height of the air outlet of the steam engine 200 can be lower, and the height of the air outlet of the steam engine 200 and the communication position of the shaft 1 can be lower, thereby shortening the length of the shaft. The length of the fluid passage in the shaft 1 enables the steam to pass through the fluid passage as soon as possible and then be discharged from the steam outlet 211 on the floor brush assembly 2 , which is beneficial to reduce the temperature loss of the steam and simplify the structure of the shaft 1 .

In one embodiment, the ratio b of the distance extending radially outward of the pallet 3 to the width of the shaft 1 is in the range of 1.8≤b≤2.2. More preferably, the range of the bearing area S of the pallet 3 is 5.9×10-3 mm ² ≤S≤6.8×10-3 mm ² . Therefore, the extension distance and bearing area of the pallet 3 are both small, so when the floor mopping mechanism 100 is used alone, the radial dimension will not be too large, and it is easier to extend into narrow areas such as the bottom of the bed for cleaning.

In order to improve the fixing stability of the steam engine 200, the surface of the pallet 3 supporting the steam engine 200 is arranged at an included angle with the shaft 1, and the included angle is an acute angle or a right angle. When the steam engine 200 is placed on the pallet 3, the center of gravity of the steam engine 200 will be biased to the direction of the shaft 1, which can prevent the steam engine 200 from sliding down from the pallet 3 to the direction away from the shaft 1, thereby helping to improve the stability of the steam engine 200. Exemplarily, the included angle between the surface of the pallet 3 supporting the steam engine 200 and the shaft 1 may be 60°, 65°, 70°, 75°, 90°, etc., which will not be listed one by one here.

Optionally, in order to improve the fixing effect of the pallet 3 on the steam engine 200 , as shown in FIG. 4 , the opposite side edges of the plate body 301 are provided with wings 34 , and the steam engine 200 is placed between the wings 34 on the opposite sides. . The two wings 34 can extend upward perpendicular to the bearing surface of the pallet 3, and of course they can also be non-perpendicular to the bearing surface of the pallet 3. For example, the two wings 34 extend away from each other or extend toward each other, as long as the steam engine 200 can be placed smoothly It is enough to reach the bearing surface of the pallet 3 . In this way, not only the steam engine 200 can be supported by the plate body 31 , but also the steam engine 200 can be prevented from shaking by the cooperation of the wings 34 on both sides, and the stability of the fixing of the steam engine 200 can be improved.

Optionally, the height of the wing plate 34 should not be too high nor too low. It can be understood that if the wing plate 34 is too high, on the one hand, it is inconvenient to install the steam engine 200, and on the other hand, it increases the volume and weight of the pallet 3, which is inconvenient for the user to operate; Bit effect is poor. Illustratively, the height of the wings 34 may be 5-10 mm.

In other embodiments, the pallet 3 may also be configured as a U-shape, V-shape, W-shape, etc., and accordingly, the bottom of the steam engine 200 matches the shape of the pallet 3 .

In some embodiments, the first guide portion 2011 may be a slide rail, and correspondingly, the second guide portion 32 may be a chute, which may also implement sliding assembly of the steam engine 200 and the pallet 3 . In other embodiments, one of the first guide portion 2011 and the second guide portion 32 is a chute, and the other is a roller. The steam engine 200 and the pallet 3 can be slidably assembled by rolling the roller along the chute.

In order to further improve the fixing effect of the pallet 3 on the steam engine 200 , the bottom surface of the steam engine 200 is further provided with a card slot 2013 , and the pallet 3 further includes an elastic protrusion 33 . When the steam engine 200 is installed on the pallet 3 , the protrusion 33 will elastically protrude from the surface of the platform and be snapped into the slot 2013 to further prevent the steam engine 200 from moving relative to the pallet 3 . Specifically, when the steam engine 200 is slidably connected to the pallet 3 , the steam engine 200 can squeeze the protrusion 33 to shrink down, so that the steam engine 200 can be smoothly connected to the pallet 3 in a sliding manner. When the steam engine 200 slides into place relative to the pallet 3, the card slot 2013 moves to just above the protrusion 33, the protrusion 33 is no longer squeezed, and the protrusion 33 bounces up and engages with the card groove 2013, thereby further fixing the steam engine 200 and pallet 3.

The height of a guide slope gradually increases in the sliding direction. When the steam engine 200 is slidably matched with the support plate from front to back, the steam engine 200 first abuts against the first guide slope, and as the steam engine 200 continues to move backward, the steam engine 200 will move backward relative to the first guide slope, and during the moving process The pushing protrusion 33 is retracted downward, so that the driving protrusion 33 is retracted into the first installation groove. It can be understood that, in order to prevent the protrusion 33 from interfering with the disassembly of the steam engine 200, the side surface of the protrusion 33 facing the shaft 1 is a second guide slope, that is, the rear surface of the protrusion 33 is a second guide slope, and the second guide slope is the second guide slope. The height of the inclined plane gradually decreases in the sliding direction. By setting the second guide slope, when the steam engine 200 slides forward relative to the pallet 3 , the steam engine 200 can cooperate with the second guide slope to push the protrusion 33 into the first installation groove, so that the protrusion 33 can avoid the steam engine 200 , to ensure the smooth disassembly of the steam engine 200.
