[0037] The embodiments of the present application are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference signs represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present application, and cannot be understood as a limitation of the present application.

[0038] ​​In the description of the utility model, if the meaning of several is one or more, the meaning of multiple is more than two, greater than, less than, more than and the like are understood as not including the number, above, below, within and the like are understood as including the number.

[0039] In the description of the utility model, unless otherwise explicitly limited, the words such as setting, installation, connection, assembly, cooperation and the like should be understood in a broad sense, and the person skilled in the art can determine the specific meaning of the above words in the utility model according to the specific content of the technical scheme.

[0040] In the description of the utility model, unless otherwise explicitly limited, the words such as setting, installation, connection, assembly, cooperation and the like should be understood in a broad sense, and the person skilled in the art can determine the specific meaning of the above words in the utility model according to the specific content of the technical scheme.

[0041] Referring to Figures 1 to 10 As shown in FIG. 1, the utility model first aspect embodiment provides a kind of chassis assembly, it is applied to heat pump equipment, chassis assembly is used as the bearing platform of heat pump equipment, heat exchanger, pipe and the like component installation, positioning, simultaneously, chassis assembly is also used to support the condensate produced in the operation process of heat pump equipment.

[0042] Referring to Figure 1 As shown in FIG. 1, it can be understood that the chassis assembly includes chassis body 100 and at least two buckle hand pieces 200. Specifically, the chassis body 100 is usually a plastic piece, on the one hand, the plastic piece is formed by injection molding, which is easy to form complex structure features, convenient for production, and low cost. On the other hand, the thermal conductivity of the plastic piece is small, which can reduce the risk of condensate at the bottom of the chassis body 100, and can avoid the condensate from falling to the ground when used indoors, thereby affecting the user's experience. And the plastic piece has good insulation and high safety.

[0043] Of course, the chassis body 100 can also be a sheet metal piece, which has high structural strength, better durability when used outdoors, and longer service life.

[0044] The first horizontal direction is the left-right direction, and the second horizontal direction is the front-rear direction, that is, the first horizontal direction is perpendicular to the second horizontal direction.

[0045] Referring to Figure 5As shown, it can be understood that the bottom of the chassis body 100 on both sides away from the first horizontal direction is respectively provided with a containing cavity 110, that is, the bottom of the left side and the right side of the chassis body 100 is provided with a containing cavity 110, and the containing cavity 110 is close to the side surface of the chassis body 100. Generally speaking, the two containing cavities 110 are symmetrically arranged. The containing cavity 110 has a first opening 111, and the first opening 111 is arranged downward.

[0046] Referring to Figures 1 to 3 As shown, it can be understood that the number of the hand buckle 200 is equal to the number of the containing cavity 110, that is, the number of the hand buckle 200 is two. The two hand buckles 200 are correspondingly fixedly installed in the two containing cavities 110, and the hand buckle 200 can be clamped, adhered or fixed on the chassis body 100 by screws, and the like, and the fixing mode of the hand buckle 200 and the chassis body 100 is not specifically limited here.

[0047] Of course, in other embodiments, the number of the hand buckle 200 can be greater than the number of the containing cavity 110, and at this time, a plurality of hand buckles 200 arranged in sequence along the second horizontal direction are installed in each containing cavity 110.

[0048] The structure of each hand buckle 200 is the same, so only one kind of mold can be used to produce the hand buckle 200, which is beneficial to reduce the mold cost and further reduce the production cost.

[0049] Referring to Figure 3 As shown, it can be understood that the bottom wall 210 of the hand buckle 200 is exposed to the first opening 111, and the bottom wall 210 of the hand buckle 200 is the downward wall surface of the hand buckle 200. Specifically, along the up-down direction (i.e. the height direction of the heat pump equipment), the maximum thickness of the hand buckle 200 is equal to the maximum depth of the containing cavity 110, or the maximum thickness of the hand buckle 200 is slightly smaller than the maximum depth of the containing cavity 110. From the bottom of the chassis assembly, the entire bottom wall 210 of the hand buckle 200 can be seen through the first opening 111. Therefore, when the heat pump equipment is transported, the hands of the installer can contact the hand buckle 200 from below the chassis assembly through the first opening 111.

[0050] It can be understood that the hand buckle 200 is a flexible piece. Specifically, the material of the hand buckle 200 can be rubber, silicone or polyurethane foam, etc., which can deform after being pressed and restore to its original state after the pressure is removed, has good energy absorption performance and deformation performance, and can provide a buffering effect. At the same time, compared with the smooth wall surface on the chassis body 100, the wall surface of the hand buckle 200 has greater friction when contacting the hands, which can prevent slipping.

[0051] Generally, heat pump equipment is quite heavy, requiring two people to lift it from the left and right sides respectively during transport. Therefore, when moving the heat pump equipment during installation, the installer places their hands under the chassis assembly and presses against the handle 200. Applying an upward force to the handle 200 lifts the heat pump equipment, facilitating transport. Because the handle 200 is a flexible component, it deforms under pressure, dispersing the pressure exerted on the installer's hands and preventing excessive localized pressure, thus improving comfort and tactile feel during transport. Furthermore, the handle 200 provides cushioning, absorbing the impact of bumps during transport and reducing the risk of hand injury. Simultaneously, the high friction between the handle 200 and the hand reduces the risk of the heat pump equipment slipping and falling, preventing injury to the installer and improving safety.

[0052] Understandably, since the receiving cavity 110 is located at the bottom of the chassis body 100, rather than on the side wall of the heat pump device's housing, it avoids the drawback of occupying internal space of the housing if the receiving cavity 110 were located on the side wall and recessed into the housing. Therefore, the receiving cavity 110's location at the bottom of the chassis body 100 does not affect the internal space of the heat pump device's housing, thus facilitating full utilization of the housing's internal space and achieving a miniaturized design. Simultaneously, the receiving cavity 110, located at the bottom of the chassis body 100, is not exposed, which improves the aesthetic appearance of the heat pump device.

[0053] Reference Figure 9 and Figure 10 As shown, it can be understood that the bottom wall 210 of the handle 200 is arranged at an angle downwards, and the ends of the bottom walls 210 of the two handles 200 that are opposite each other along the first horizontal direction are lower than the ends that are facing each other along the first horizontal direction. The end of each handle 200 (or the bottom wall 210 of the handle 200) located away from the middle position of the chassis body 100 along the first horizontal direction is defined as the first end 260, and the end located closer to the middle position of the chassis body 100 along the first horizontal direction is defined as the second end 270. That is, the first end 260 of the bottom wall 210 of each handle 200 is lower than the second end 270. Therefore, when handling the heat pump equipment, the installer's palm contacts the bottom wall 210 of the handle 200 and is placed in a V-shape or U-shape against the chassis assembly, thereby further reducing the risk of slipping and improving safety.

[0054] It can be understood that the accommodating cavity 110 has a cavity wall 113 facing downward, that is, the inner wall surface of the accommodating cavity 110 facing downward. If the end of the cavity wall 113 away from the middle position of the base body 100 along the first horizontal direction is lower than the end close to the middle position of the base body 100 along the first horizontal direction, the thickness of the handgrip 200 along the up-down direction can be equal everywhere in the first horizontal direction, and when the handgrip 200 is attached to the cavity wall 113, the bottom wall 210 of the handgrip 200 is arranged obliquely, which can further reduce the risk of hand slipping.

[0055] Referring to Figure 9 and Figure 10 It can be understood that in the present embodiment, the cavity wall 113 is perpendicular to the up-down direction. Among the two handgrips 200, the thickness of at least part of the structure of one handgrip 200 increases in the first horizontal direction away from the other handgrip 200. For example, the thickness of the entire handgrip 200 increases in the first horizontal direction away from the other handgrip 200, that is, in each handgrip 200, the thickness of the first end 260 of the handgrip 200 is greater than the thickness of the second end 270, and the thickness of the handgrip 200 increases from the second end 270 to the first end 260. Therefore, when the handgrip 200 is attached to the cavity wall 113, the bottom wall 210 of the handgrip 200 is arranged obliquely, which can further reduce the risk of hand slipping.

[0056] The connection structure between the handgrip 200 located on one side of the base body 100 along the first horizontal direction and the base body 100 will be described in detail below, and the structure on the other side can be referred to the structure on this side.

[0057] Referring to Figure 3 , Figure 5 and Figure 6As shown, it can be understood that the hand buckle 200 is connected with the chassis body 100 in a snap-fit manner, that is, the hand buckle 200 is snap-fitted to the chassis body 100. Specifically, the cavity wall 113 is provided with a first snap-fit portion 114, which is provided in a downward protruding manner. In a cross section perpendicular to the second horizontal direction, the cross section of the first snap-fit portion 114 is substantially L-shaped. Correspondingly, the hand buckle 200 is provided with a clamping hole 220, which penetrates the wall surface on both sides of the hand buckle 200 in the up-down direction. Similarly, in a cross section perpendicular to the second horizontal direction, the cross section of the clamping hole 220 is substantially L-shaped. The first snap-fit portion 114 is arranged in the clamping hole 220, and the first snap-fit portion 114 in the L-shaped structure is snap-fitted to the hand buckle 200. Therefore, the first snap-fit portion 114 can limit the hand buckle 200 from being separated downward from the chassis body 100, and since the first snap-fit portion 114 is arranged in the clamping hole 220, the first snap-fit portion 114 can also limit the hand buckle 200 from moving relative to the chassis body 100 in the front-rear direction or the left-right direction, so as to realize that the hand buckle 200 is snap-fitted to the chassis body 100, and the connection is reliable. Since the hand buckle 200 can be deformed under the action of an external force, when the hand buckle 200 is installed, the first snap-fit portion 114 is aligned with the clamping hole 220, the hand buckle 200 is pressed against the cavity wall 113, and the first snap-fit portion 114 is pressed into the clamping hole 220, so that the installation operation is convenient, without any screw, and the structure is simple.

[0058] In the embodiment, the number of the first snap-fit portions 114 is three, and the three first snap-fit portions 114 are arranged at equal intervals along the second horizontal direction. Correspondingly, the hand buckle 200 is provided with clamping holes 220 corresponding to the first snap-fit portions 114 one by one, and the three first snap-fit portions 114 are arranged in the three clamping holes 220 and are snap-fitted to the hand buckle 200. Therefore, the connection reliability of the hand buckle 200 and the chassis body 100 can be improved, and the hand buckle 200 can be prevented from rotating relative to the chassis body 100, and the installation stability of the hand buckle 200 is improved.

[0059] Of course, the number of the first snap-fit portions 114 can also be two, four, five or more, and the number of the first snap-fit portions 114 is not specifically limited here.

[0060] Referring to Figure 3 , Figure 5 and Figure 6As shown, it can be understood that the cavity wall 113 is further provided with a second buckle part 115, which is located on one side of the first buckle part 114 away from the middle position of the base body 100 along the first horizontal direction, and the second buckle part 115 is arranged and extends along the first horizontal direction and extends to the side wall of the base body 100. Correspondingly, the hand buckle 200 is provided with a clamping groove 230 on one side of the cavity wall 113, which is arranged along the first horizontal direction, and the clamping groove 230 extends to the first end 260 of the hand buckle 200 and is provided with a notch 231, that is, the notch 231 faces the first horizontal direction. The second buckle part can be inserted into the clamping groove 230 through the notch 231, so that the second buckle part and the hand buckle 200 are clamped and matched. In this way, the second buckle part can increase the limiting of the hand buckle 200 in the second horizontal direction, and further improve the installation stability of the hand buckle 200.

[0061] Referring to Figure 5 As shown, it can be understood that the second buckle part 115 includes two clamping plates 1151, which are arranged in sequence along the second horizontal direction, and the two clamping plates 1151 are arranged obliquely, and the distance between the two clamping plates 1151 in the second horizontal direction increases from top to bottom. That is, the two clamping plates 1151 are distributed in a V shape, and the opening of the V shape faces downward. Correspondingly, the two groove walls of the clamping groove 230 arranged oppositely along the second horizontal direction are arranged in a V shape. Therefore, when the two clamping plates 1151 of the second buckle part 115 are inserted into the clamping groove 230, the second buckle part 115 and the hand buckle 200 form a constraint in the upward and downward direction, that is, the second buckle part 115 can limit the hand buckle 200 from being separated downward from the base body 100, further improving the installation stability of the hand buckle 200.

[0062] In this embodiment, the number of the second buckle part 115 is four, and the four second buckle parts 115 are arranged at intervals along the second horizontal direction. Correspondingly, the hand buckle 200 is provided with a clamping groove 230 corresponding to the second buckle part 115, and the four second buckle parts 115 are correspondingly inserted into the four clamping grooves 230 and clamped and matched with the hand buckle 200. Therefore, the connection reliability of the hand buckle 200 and the base body 100 can be further improved, and the installation stability of the hand buckle 200 can be improved.

[0063] Of course, the number of the second buckle part 115 can also be three, five, six or more, and the number of the second buckle part 115 is not specifically limited here.

[0064] Therefore, when installing the handle 200, the handle 200 is deformed, for example, the handle 200 is bent at a certain angle, the notch 231 of the clamping groove 230 is aligned with one end of the second clamping portion 115 close to the first clamping portion 114, the handle 200 is pushed in the first horizontal direction, and the second clamping portion 115 is inserted into the clamping groove 230 until the second clamping portion 115 is completely accommodated in the clamping groove 230. At this time, the first clamping portion 114 is aligned with the clamping hole 220 in the up-down direction, and then the handle 200 is pressed towards the cavity wall 113, so that the first clamping portion 114 is pressed into the clamping hole 220. In this way, the first clamping portion 114 and the second clamping portion 115 are both clamped and matched with the handle 200, so that the handle 200 is fixedly installed in the accommodation cavity 110, and the installation is stable, without any screws, and the operation is convenient.

[0065] Referring to Figure 1 , Figure 3 and Figure 4 It can be understood that the inner side is defined as the side close to the middle position of the base body 100 along the first horizontal direction, and the outer side is defined as the side away from the middle position of the base body 100 along the first horizontal direction. The side of the accommodation cavity 110 along the first horizontal direction has a second opening 112, and the second opening 112 faces the outer side of the base body 100, that is, the second opening 112 faces away from the middle position of the base body 100 along the first horizontal direction. That is, the lower side and the outer side along the first horizontal direction of the accommodation cavity 110 are both open. The base body 100 includes a baffle 120 located at the second opening 112. In the second horizontal direction, the baffle 120 extends to both ends of the second opening 112, and in the up-down direction, the baffle 120 extends downward from the cavity wall 113. After the handle 200 is installed in the accommodation cavity 110, the first end 260 of the handle 200 abuts against the side of the baffle 120 facing the accommodation cavity 110. Therefore, the baffle 120 can limit the handle 200 from separating from the base body 100 along the first horizontal direction to the outer side. Especially when the installer carries the heat pump equipment, the hand will exert a pulling force on the handle 200 along the first horizontal direction outward, which is opposite to the friction direction between the hand and the handle 200. The baffle 120 exerts a pushing force on the handle 200 along the first horizontal direction inward, so that the pushing force can offset a part of the pulling force, further reducing the risk of the handle 200 separating from the base body 100 along the first horizontal direction outward, and improving the installation stability of the handle 200.

[0066] Referring to Figure 3 and Figure 4As shown, it can be understood that, in general, the height dimension of the baffle 120 is less than the height dimension of the second opening 112 in the up-down direction. Therefore, when the hand of the installer is in contact with the handgrip 200 and lifts the heat pump device, the hand can be prevented from being pressed against the baffle 120 to cause excessive local pressure on the hand, thereby reducing the risk of injury.

[0067] Referring to Figure 3 and Figure 6 As shown, it can be understood that the handgrip 200 includes an extension 240, which is located at the first end 260, i.e., the extension 240 is located at the end of the handgrip 200 close to the second opening 112 in the first horizontal direction. The extension 240 is outwardly protruding in the first horizontal direction, and the extension 240 is located below the baffle 120. Therefore, when the hand of the installer is in contact with the handgrip 200 and lifts the heat pump device, the hand is in contact with the extension 240 at a position below the baffle 120, thereby preventing the hand from being pressed against the baffle 120 to cause excessive local pressure on the hand, and the extension 240 can disperse the pressure exerted by the heat pump device on the curved part of the hand of the installer, thereby preventing the hand from being pressed too hard and improving the comfort of the hand during the carrying process.

[0068] It is easy to understand that, when the hand of the installer is in contact with the handgrip 200 and lifts the heat pump device, the closer the position to the connection between the bottom surface and the side surface of the chassis body 100 (i.e., the position of the finger bend, or the first end 260 of the handgrip 200) in the first horizontal direction, the greater the pressure on the hand, and the greater the pressure and deformation on the handgrip 200.

[0069] Therefore, the thickness of at least part of the structure of the handgrip 200 is increased from the second end 270 to the first end 260, i.e., the thickness of the first end 260 is larger, for example, the thickness of the entire handgrip 200 is increased from the second end 270 to the first end 260. This allows the handgrip 200 to withstand a larger deformation and a larger pressure at the first end 260, thereby ensuring that the bottom wall 210 of the handgrip 200 is arranged obliquely, reducing the risk of falling off the hand. At the same time, the pressure on the position of the finger bend is more dispersed, the comfort is better, and the risk of injury is reduced.

[0070] In this embodiment, the thickness of the structure of the other components of the handgrip 200 is increased from the second end 270 to the first end 260, except for the structure of the extension 240.

[0071] Referring to Figure 9 and Figure 10 ​As shown, it can be understood that the extension 240 is provided with a rounded corner 241 located at the junction of the wall surface on the side of the extension 240 away from the baffle 120 and the wall surface of the extension 240 on the outer side of the chassis body 100 in the first horizontal direction. That is, the rounded corner 241 is located at the outer corner of the lower side of the extension 240. Therefore, when the hand of the installer is in contact with the handgrip 200 and lifts the heat pump equipment, the rounded corner 241 corresponds to the bending part of the fingers, so that the bending part of the fingers is more fitted with the handgrip 200, the contact area between the fingers and the handgrip 200 is increased, the pressure borne by the fingers is further dispersed, the comfort is better, and the risk of injury is reduced.

[0072] Referring to Figure 7 and Figure 8 As shown, it can be understood that the bottom wall 210 of the handgrip 200 is provided with a plurality of grooves 250, the grooves 250 are arranged in the first horizontal direction and extend through the wall surfaces on both sides of the handgrip 200 in the first horizontal direction. The plurality of grooves 250 are arranged in the second horizontal direction. In the embodiment, the number of grooves 250 is eight. Therefore, when the hand of the installer is in contact with the handgrip 200 and lifts the heat pump equipment, the fingers of the hand are respectively accommodated in the plurality of grooves 250, so that the fingers are fitted with the handgrip 200, the contact area between the fingers and the handgrip 200 is increased, the pressure borne by the fingers is further dispersed, the comfort is improved, and the risk of injury is reduced.

[0073] Referring to Figure 7 As shown, it can be understood that the junctions of the groove walls of the grooves 250 and the bottom wall 210 of the handgrip 200 are all smooth curved surfaces, and in the cross section perpendicular to the first horizontal direction, the cross section of the groove wall of the groove 250 is an arc segment, which is more matched with the shape of the fingers. The cross section of the combination of the groove walls of the plurality of grooves 250 and the bottom wall 210 of the handgrip 200 is a wavy line. Therefore, the fingers are more fitted with the handgrip 200, the pressure borne by the fingers is further dispersed, and the ergonomics is met.

[0074] Since the number of grooves 250 is eight, generally, only four fingers are in contact with the bottom wall 210 of the handgrip 200. Therefore, no matter where the hand is located in the handgrip 200 in the second horizontal direction, the four fingers can be accommodated in the plurality of grooves 250 to ensure that the fingers are fitted with the handgrip 200, the pressure is dispersed, and the risk of injury is reduced.

[0075] Of course, the number of grooves 250 can also be six, seven, nine or more, and the number of grooves 250 is not specifically limited here.

[0076] Referring to Figure 1As shown, it can be understood that the accommodating cavity 110 extends from the middle of the chassis body 100 to one side along the second horizontal direction. For example, the accommodating cavity 110 extends from the middle of the chassis body 100 to the rear along the second horizontal direction, that is, the accommodating cavity 110 is more biased to the rear. Therefore, when carrying the heat pump equipment, the installers on both sides of the heat pump equipment can respectively place one hand on the bottom of the chassis assembly at the middle position along the second horizontal direction to carry the heat pump equipment. Alternatively, the installers on both sides carry the heat pump equipment by both hands, that is, one hand is placed on the bottom of the chassis assembly at the rear position along the second horizontal direction, and the other hand is placed on the front panel of the heat pump equipment. In this way, different carrying methods can be provided to match the carrying habits of different personnel, facilitating carrying and installation.

[0077] Of course, the accommodating cavity 110 can also extend from the middle of the chassis body 100 to the front along the second horizontal direction, that is, the accommodating cavity 110 is more biased to the front. When the installers carry the heat pump equipment by both hands, one hand is placed on the bottom of the chassis assembly at the front position along the second horizontal direction, and the other hand is placed on the rear panel of the heat pump equipment.

[0078] It is easy to understand that for the chassis body 100 which is a plastic part, in order to ensure the structural strength thereof, the chassis body 100 is provided with a large number of reinforcing ribs to increase the structural stability of the chassis body 100. However, in the accommodating cavity 110, there is no reinforcing rib in order to ensure smooth demolding.

[0079] Referring to Figure 1 and Figure 4 As shown, it can be understood that the chassis body 100 includes a bottom plate 130 and a side plate 140, the side plate 140 is annular and connected to the upper side of the bottom plate 130, and the side plate 140 extends upward. In order to ensure the structural strength of the position where the accommodating cavity 110 is located, the chassis body 100 further includes a reinforcing rib, which is connected between the outer side wall of the side plate 140 (i.e. the side away from the space surrounded by the side plate 140) and the bottom plate 130, and the reinforcing rib is located above the accommodating cavity 110. Therefore, the reinforcing rib here can make up for the problem of structural strength reduction caused by the arrangement of the accommodating cavity 110, thereby enhancing the structural strength of the chassis body 100 as a whole.

[0080] Referring to Figure 4As shown, it can be understood that the reinforcing ribs include the first reinforcing rib 150, the second reinforcing rib 160 and the third reinforcing rib 170, wherein, in the cross section perpendicular to the first horizontal direction, the cross section of the first reinforcing rib 150 is a circular ring, the second reinforcing rib 160 is arranged along the up-down direction and connected with the first reinforcing rib 150, and the third reinforcing rib 170 is arranged along the second horizontal direction and connected with the first reinforcing rib 150. The number of the first reinforcing rib 150, the second reinforcing rib 160 and the third reinforcing rib 170 is multiple, the multiple first reinforcing ribs 150 are arranged in a rectangular array, and the multiple second reinforcing ribs 160 and the multiple third reinforcing ribs 170 are also arranged in a rectangular array. That is to say, the second reinforcing rib 160 and the third reinforcing rib 170 are perpendicular to each other and connected at the intersection through the first reinforcing rib 150. The reinforcing rib with the combined structure has higher structural strength and better structural stability, which is beneficial to enhancing the structural strength of the chassis body 100.

[0081] It can be easily understood that a sealing strip 180 is usually arranged between the chassis body 100 and the side wall of the shell, and the sealing strip 180 is arranged around the side plate 140 of the chassis body 100. At the position of the reinforcing rib, the sealing strip 180 abuts against the wall surface of the reinforcing rib facing the outer side along the first horizontal direction.

[0082] Connecting the intersection of the second reinforcing rib 160 and the third reinforcing rib 170 through the circular ring-shaped first reinforcing rib 150 can increase the area of the wall surface of the first reinforcing rib 150, the second reinforcing rib 160 and the third reinforcing rib 170 facing the outer side along the first horizontal direction, thereby increasing the contact area of the sealing strip 180 and the whole of the first reinforcing rib 150, the second reinforcing rib 160 and the third reinforcing rib 170, so that the whole of the first reinforcing rib 150, the second reinforcing rib 160 and the third reinforcing rib 170 can provide sufficient support for the sealing strip 180, avoiding excessive deformation of the sealing strip 180, thereby effectively ensuring the sealing between the chassis body 100 and the side wall of the shell.

[0083] Of course, the first horizontal direction can be the front-rear direction, and the second horizontal direction is the left-right direction. Compared with the above embodiment, the difference lies in the different positions of the accommodating cavity 110 on the chassis body 100 and the different positions of the handgrip 200 on the chassis body 100. Here, no longer be repeated.

[0085] The heat pump device has at least all the beneficial effects brought by the technical solutions of the above-mentioned embodiments due to adoption of the chassis assembly.

[0086] The embodiments of the utility model are described in detail above in combination with the drawings, but the utility model is not limited to the above-mentioned embodiments, and various changes can be made within the knowledge range possessed by the ordinary skilled in the art without departing from the purpose of the utility model.
