Filtering unit 150 is installed in the compartment 101 to install filter (see figure 2 or 6) of the main body. However, when filtering unit 150 is assembled, or when the first filter element 170 is not fully engages with the housing 152 of the filter, the safety lever 153 is in the direction of one side of the filter node 150 and prevents the installation of filter node in the compartment 101 for installation of the filter facing one side wall, as shown in Fig.6, and, thus, preventing the installation of the filter node 150 in the compartment 101 for installation of the filter. In other words, the safety lever 153 provides that the unit is operational only when the completed Assembly of the filter node 150.

Design and operation of the safety lever 153 will be described in more detail with reference to figure 4 and 5.

As shown in figure 4, the safety lever 153 has a locking protrusion a, which can be inserted into the hole at back is their 156, formed in the side wall of the housing 152 of the filter. When the first filter element 170 is inserted into the housing 152 of the filter in the direction shown by the arrow C (figure 5), the safety lever 153 with the locking protrusion a stalkivaetsja in the housing 152 of the first filter holder 172 of the filter.

When filtering unit 150 is fully assembled, as described above, the safety lever 153 is located inside the housing 152 of the filter such that the filtering unit 150 may be inserted into the compartment 101 for installation of the filter. If filtering unit 150 is assembled incompletely or incorrectly, it can not be inserted into the compartment 101 for installation of the filter, thus preventing the possibility of incomplete filtering, due to an incomplete Assembly of the filter node 150.

Figure 9 shows the filtering unit 150 after installation in the compartment 101 for installation of the filter. On Fig shows the internal construction of the compartment 101 for installation of the filter.

As shown in Fig.7, the filtering unit 150 connected to the cover 120 of the main body is inserted into the compartment 101 to set a filter or extracted from it. Below I will describe how to install the filter node 150, Saedinenie cover 120 of the main body, in compartment 101 for installation of the filter.

To install filtering unit 150 in the compartment 101 to set a filter, the user must hold the handle 121 located on the lid 120 of the main body, and a sliding insert in a downward direction of the second guide element 152b formed on the filter node 150 (7), along the inner side of the first guide element 103 formed in the compartment 101 to install filter (see Fig). Before the housing 150 of the filter is inserted in the compartment 101 to install the filter cover holes 158 closes the hole 155 formed in the housing 152 of the filter, under the action of the elastic force of the spring 159, as shown in Fig.7.

During installation of the filter node 150 in the compartment 101 for mounting the filter, the bottom of the cover 158 holes collides with the upper part of the sealing element 102 (see Fig)formed on one side of the compartment 101 for installation of the filter. Collision with protruding upper part of the sealing element 102 causes lifting of the cover holes 158 in the direction indicated by the arrow D in figure 9, overcoming the return force of the spring 159, seeking to hold the cover 158 in the closed position, to open the hole 155 of the housing 152 of the filter. Thus, when filtering unit 150 is fully inserted into the Bay 101 for installation of the filter hole 55 of the housing 152 of the filter exactly is combined with a hole 104 for suction of air (see Fig) to allow the connection of a flexible hose 180 (see figure 2).

The user can retrieve filtering unit 150 of the cover 101 for installation of the filter, hold the handle 121 of the cover 120 of the main body, for cleaning the filter node 150. In the extraction process cover holes 158 is released from contact with the sealing element 102 and is returned to its original position, closing the opening 155 of the housing 152 of the filter, under the action of the return force of the spring 159 (see Fig.7).

Thus, when the user simply inserts the filtering unit 150 using the second guide element 152b to enter into engagement with the inner side of the first guide element 103, the hole 155 of the filter node 150 will automatically be aligned with the hole 104 to the suction air of the main body 100. When you need to extract the filtering unit 150 of the cover 101 to install a filter for filtering node 150, the user need only lift the lid 120 of the main body, while holding the handle 121. In this case, the cover 158 holes will close the opening 155 to prevent particles of dust out of the filter node 150 over a period of time when filtering unit remains outside the compartment 101 for installation of the filter.

Figure 10-12 shows the connection of the filter node 150 and it is iski 120 of the main body and the process of terminating the connection. Figure 10 shows a perspective view of the partially disassembled cover 120 of the main body and the housing 152 of the filter to describe the connection of these two elements. Figure 11 and 12 shows detailed views showing the connection of the filter housing with the cover main body and the reverse process of separation of these two elements.

As shown in figure 10, the cover 120 of the main body has first, second and third hooks 122, 123, 124, respectively, located on its bottom or end wall. The first hook 122 is formed in the center of one side of the bottom wall. The second hook 123 and the third hook 124 is formed on the other side of the bottom wall at a given distance from each other. The first hook 122 is kept loaded in the direction shown by the arrow X in Fig. 10, an elastic spring (not shown). In addition, the housing 152 of the filter includes the captured loop 154 located on its top surface, and has a lot of locking hooks 157 formed on the same surface on both sides of its upper part.

In addition, on one side of the housing 152 of the filter formed by the supporting ledge 302 and a plurality of latches 301 for holding the cleaning tool filter. Figure 10 as an example of the cleaning tool shown brush 300.

Figure 11 shows a detailed view in partial section of the cover 120 of the main body and KOR the USA 152 of the filter in the United state. When the cover 120 of the main body close to the body 152 of the filter in the direction shown by the arrow F, and the second and third hooks 123, 124 engages with the locking hooks 157 (figure 10), the first hook 122 can engage with captured hinge 154, as shown in figure 11.

The user can easily separate the housing 152 of the filter from the lid 120 of the main body by the ascent of the first hook 122 in the direction shown by the arrow G in Fig, thus, releasing the first hook 122 from the corresponding captured hinge 154.

As described above, the cover 120 of the main body and the housing 152 of the filter can be easily connected and disconnected. Thus, the user can easily set the filtering unit 150 in the compartment 101 for installation of the filter and remove it using the handle 121, without dirtying his or her hands. On Fig shows the main body 100 to describe the connection of the handle 121 on the cover 120 of the main body, the main body 100. As shown in Fig, on both sides of the handle 121 is formed of the fourth hook 105 and the fifth hook 106, and in the appropriate locations in the main body 100 formed of two corresponding cut-out 107. If filtering unit 150 is inserted into the compartment 101 for installation of the filter and the handle 121 located on the lid 120 of the main body, pressed down, the fourth and fifth hooks 105, 106 will Zap the you in the cutouts 107, thus, connecting the handle 121 of the main body 100 in the retracted position.

Because the handle 121 is connected with the main body 100, the cover 120 of the main body will not be separated from the main body 100, even if the main body 100 turn sharply at work.
