[0040] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.
[0041] Cleaning equipment such as handheld cleaning machines and autonomous cleaning robots are usually equipped with negative pressure components, such as fans and vacuum pumps, which provide suction to form a dust-collecting airflow, which sucks dust, particles and other garbage into the cleaning equipment to achieve the cleaning purpose. However, when the cleaning equipment is performing cleaning tasks, the negative pressure component will vibrate, causing the cleaning equipment to resonate, resulting in unstable operation of the cleaning equipment and affecting the normal operation of the cleaning equipment.
[0042] In order to solve the technical problems existing in the above-mentioned related prior art, refer to Figure 1 The embodiment of the utility model provides a negative pressure assembly installation structure 1, which is applied to a cleaning device, wherein the cleaning device includes a negative pressure assembly 2, so as to improve the shock absorption effect of the negative pressure assembly 2 while installing the negative pressure assembly 2, and ensure the working stability of the cleaning device. The cleaning device may include a handheld cleaning machine, etc., and the negative pressure assembly 2 may include a negative pressure fan, a negative pressure vacuum pump, etc., without limitation.
[0043] Reference Figure 2 and Figure 3 The mounting structure 1 includes: a bracket 11 and a shock absorbing member 12. The bracket 11 is arranged on the cleaning equipment and is used to install the negative pressure component 2. The shock absorbing member 12 is connected between the bracket 11 and the negative pressure component 2, and the shock absorbing member 12 and the bracket 11 are clearance-matched.
[0044] The mounting structure 1 mentioned in this embodiment is used to install the negative pressure component 2, and the negative pressure component 2 is installed on the cleaning equipment through the mounting structure 1. Among them, when the mounting structure 1 is set on the cleaning equipment, it is connected to the cleaning equipment through the bracket 11 to achieve installation and fixation on the cleaning equipment. Among them, the connection form can be screw connection, snap connection, etc. Exemplarily, the bracket 11 is provided with a plurality of supporting feet, and the plurality of supporting feet are located on the circumference of the bracket 11, and each supporting foot is respectively provided with a connecting hole 110, and the bracket 11 can be connected to the cleaning equipment by inserting screws through the connecting holes 110 of the plurality of supporting feet. This is only exemplary and not restrictive.
[0045] When the negative pressure assembly 2 is installed on the bracket 11, it is connected to the bracket 11 through the shock absorber 12. Specifically, the shock absorber 12 can be connected to the negative pressure assembly 2 first, and then the shock absorber 12 can be connected to the bracket 11, so as to realize the installation of the negative pressure assembly 2 on the bracket 11. Therefore, when the negative pressure assembly 2 generates vibration during operation, the shock absorber 12 can be used to reduce vibration between the negative pressure assembly 2 and the bracket 11. Optionally, a placement position can be set on the bracket 11 for placing the negative pressure assembly 2. As an example, the placement position of the bracket 11 is configured with a receiving groove adapted to the negative pressure assembly 2. When the negative pressure assembly 2 is set on the bracket 11, it is accommodated in the receiving groove of the bracket 11 together with the shock absorber 12. Among them, a detachable connection can be adopted between the negative pressure assembly 2 and the shock absorber 12, and between the shock absorber 12 and the bracket 11. The detachable connection between the two can be the same or different, and can be set according to actual conditions. The detachable connection form can be such as a snap connection, a sleeve connection, etc. Optionally, one or more shock absorbers 12 may be provided, depending on the actual situation. The shock absorber 12 comprises an elastic material or is made of a flexible material. For example, the shock absorber 12 may be made of a soft rubber material, but is not limited thereto. Furthermore, the shock absorber 12 and the bracket 11 are clearance matched, and clearance match refers to a match with a gap (the minimum gap is greater than zero) between the shock absorber 12 and the bracket 11. That is, when the shock absorber 12 is connected to the bracket 11, there is a gap between the two. In some embodiments, the gap between the shock absorber 12 and the bracket 11 may be uniform. It is also understandable that the gap may be regular or uneven, as long as there is a gap greater than zero between the two, and there is no restriction on the shape and length of the gap. In the case of clearance match, the shock absorber 12 can move within a certain range relative to the bracket 11.
[0046] In the technical solution of the present utility model, the vibration generated by the negative pressure component 2 during operation will be transmitted to the shock absorbing component 12 for shock absorption by the shock absorbing component 12; and, due to the clearance fit between the shock absorbing component 12 and the bracket 11, the shock absorbing component 12 will collide with the bracket 11 when transmitting the vibration to the bracket 11, so that the vibration transmitted to the bracket 11 is greatly weakened, thereby reducing the impact of the vibration of the negative pressure component 2 on the cleaning equipment and improving the working stability of the cleaning equipment.
[0047] In some embodiments, multiple gaps are formed between the shock absorber 12 and the outer peripheral surface of the bracket 11 in different directions. Among them, multiple gaps may be formed between the shock absorber 12 and the outer peripheral surface of the bracket 11 in the upper direction, the lower direction, the left direction, the right direction, etc., including but not limited to these. The shock absorber 12 forms multiple gaps with the outer peripheral surface of the bracket 11 in different directions, so that the collision direction and collision position of the shock absorber 12 and the bracket 11 are wider, and the collision position is more, which can further enhance the effect of weakening the vibration transmitted to the bracket 11.
[0048] In some embodiments, reference Figures 3 to 6 , the shock absorber 12 includes a first body 121 and a second body 122 connected to each other, the first body 121 is sleeved on the negative pressure assembly 2, and the second body 122 is connected to the bracket 11 and has a clearance fit with the bracket 11. In this embodiment, the shock absorber 12 includes a first body 121 and a second body 122, and the first body 121 is connected to the second body 122. Optionally, the first body 121 and the second body 122 are integrally formed. The first body 121 is a part of the shock absorber 12 for connecting with the negative pressure assembly 2, and is sleeved with the negative pressure assembly 2. Optionally, the first body 121 is cylindrical and the inner diameter of the first body 121 is adapted to the outer diameter of the negative pressure assembly 2, and the first body 121 is sleeved on the peripheral side of the negative pressure assembly 2. The second body 122 is another part of the shock absorber 12 for connecting with the bracket 11, and is used to connect with the bracket 11 and has a clearance fit with the bracket 11. Among them, the structural structure of the second body 122 can be various, for example, the second body 122 can be a special-shaped shape, and is plugged and connected with the bracket 11. Further, taking the first body 121 as an example, the second body 122 can be convexly arranged on the outer surface of the first body 121. Optionally, there are multiple second bodies 122, and the multiple second bodies 122 are arranged at different positions of the first body 121 and are respectively connected to the first body 121. It is easy to understand that when the vibration generated by the negative pressure component 2 is transmitted to the shock absorber 12, it is first transmitted to the first body 121 of the shock absorber 12, and then transmitted to the second body 122 through the first body 121. Since the second body 122 of the shock absorber 12 is in clearance with the bracket 11, the second body 122 will collide with the bracket 11 when transmitting the vibration to the bracket 11, thereby greatly weakening the vibration transmitted to the bracket 11.
[0049] In some embodiments, reference Figures 5 to 8, the bracket 11 is provided with a connecting hole 110, and the second body 122 includes a first connecting portion 1221 and a second connecting portion 1222, the first connecting portion 1221 is connected to the first body 121, and the second connecting portion 1222 is penetrated in the connecting hole 110 and is gapped with the hole wall of the connecting hole 110. In this embodiment, the second body 122 includes a first connecting portion 1221 and a second connecting portion 1222. Optionally, the first connecting portion 1221 and the second connecting portion 1222 are integrally formed, and an angle is formed between the second connecting portion 1222 and the first connecting portion 1221. The specific angle of the angle can be set according to actual conditions, such as 90°. In the second body 122, its first connecting portion 1221 is connected to the first body 121, and when connected to the bracket 11, the second body 122 is penetrated in the connecting hole 110 through its second connecting portion 1222 and is gapped with the connecting hole 110. That is, the diameter of the connection hole 110 is slightly larger than the outer diameter of the second connection portion 1222, and when the second connection portion 1222 is inserted into the connection hole 110, there is a gap between the outer wall of the second connection portion 1222 and the hole wall of the connection hole 110. Therefore, when the second body 122 transmits vibration to the bracket 11, the second connection portion 1222 can move in the connection hole 110 along the radial direction of the connection hole 110, so as to reciprocate and collide with the hole wall of the connection hole 110 of the bracket 11, thereby greatly weakening the vibration transmitted to the bracket 11.
[0050] In some embodiments, reference Figure 6 The second connection part 1222 is formed with a first step surface 1222A and a connection section 1222B extending perpendicular to the first step surface 1222A. The connection section 1222B is accommodated in the connection hole 110 and cooperates with the hole wall of the connection hole 110 to form a first gap 100. The first step surface 1222A cooperates with the peripheral gap of one end of the connection hole 110 to form a second gap 200. Specifically, when the second connection part 1222 is inserted into the connection hole 110, its connection end is accommodated in the connection hole 110 and has a first gap 100 between it and the hole wall of the connection hole 110; and the first step surface 1222A of the second connection part 1222 is located in the direction of one end of the connection hole 110 and has a second gap 200 between it and the peripheral edge of one end of the connection hole 110. Through the first gap 100 and the second gap 200, when the second body 122 transmits vibration to the bracket 11, the second connecting portion 1222 can move in the connecting hole 110 along the radial direction of the connecting hole 110 to reciprocately collide with the hole wall of the connecting hole 110 through the connecting section 1222B, and can also move in the axial direction of the connecting hole 110 to reciprocately collide with the periphery of one end of the connecting hole 110 through the first step surface 1222A. That is, the second connecting portion 1222 penetrated through the connecting hole 110 can move in multiple directions and more flexibly, thereby being able to greatly weaken the vibration transmitted to the bracket 11.
[0051] In some embodiments, the width of the first gap 100 is 0.1 mm-1 mm; and / or, the width of the second gap 200 is 0.1 mm-1 mm; and / or, referring to Figure 6 The second connection portion 1222 is also formed with a second step surface 1222C opposite to the first step surface 1222A, the connection section 1222B is located between the first step surface 1222A and the second step surface 1222C, and the periphery of the other end of the connection hole 110 abuts against the second step surface 1222C.
[0052] In this embodiment, optionally, the width range of the first gap 100 is selected and set between 0.1mm and 1mm. For example, the width of the first gap 100 can be set to 0.1mm, 0.5mm or 1mm, etc., according to the actual situation. Among them, in actual application, the specific width of the first gap 100 can be set according to the vibration intensity of the negative pressure component 2. For example, the vibration intensity of the negative pressure component 2 is strong, and the first gap 100 is set to a larger width; the vibration intensity of the negative pressure component 2 is weak, and the first gap 100 is set to a smaller width. As an example, when the vibration intensity of the negative pressure component 2 is strong, the width of the first gap 100 can be set to 1mm; when the vibration intensity of the negative pressure component 2 is medium, the width of the first gap 100 can be set to 0.5mm; when the vibration intensity of the negative pressure component 2 is weak, the width of the first gap 100 can be set to 0.1mm.
[0053] Optionally, the width range of the second gap 200 is selected and set between 0.1mm and 1mm. For example, the width of the first gap 100 can be set to 0.1mm, 0.4mm or 1mm, etc., according to actual conditions. Among them, in actual application, the specific width of the second gap 200 can be set according to the vibration intensity of the negative pressure component 2. For example, if the vibration intensity of the negative pressure component 2 is strong, the second gap 200 is set to a larger width; if the vibration intensity of the negative pressure component 2 is weak, the second gap 200 is set to a smaller width. As an example, when the vibration intensity of the negative pressure component 2 is strong, the width of the second gap 200 can be set to 1mm; when the vibration intensity of the negative pressure component 2 is medium, the width of the second gap 200 can be set to 0.4mm; when the vibration intensity of the negative pressure component 2 is weak, the width of the second gap 200 can be set to 0.1mm.
[0054] Optionally, when the second connection portion 1222 is inserted into the connection hole 110, the second connection portion 1222 has a connection end accommodated in the connection hole 110, and the first step surface 1222A is located in the direction of one end of the connection hole 110, and its second step surface 1222C is located in the direction of the other end of the connection hole 110, and abuts against the periphery of the other end of the connection hole 110. It is easy to understand that the second connection portion 1222 abuts against the periphery of the other end of the connection hole 110 through the second step surface 1222C to form a movable limit in the connection hole 110, which can prevent the second connection portion 1222 from detaching from the connection hole 110 during the vibration transmission process, thereby ensuring the connection stability of the second connection portion 1222 and the bracket 11.
[0055] In some embodiments, reference Figure 2 , Figure 7 and Figure 8 The first body 121 is provided with a clamping portion 1211, the position of the clamping portion 1211 corresponds to the position of the second body 122, and is spaced from the second body 122. A receiving groove 1223 is provided at the connection between the second body 122 and the first body 121. The negative pressure assembly 2 includes an air pump, and the air pump includes an air pump body 21 and an air pipe 22. The first body 121 is sleeved on the air pump body 21, and the air pipe 22 is accommodated in the receiving groove 1223 and abuts against the clamping portion 1211. In this embodiment, when the negative pressure assembly 2 is installed on the first body 121, the air pump body 21 of the air pump is sleeved through the first body 121, and the air pipe 22 is accommodated in the receiving groove 1223 of the second body 122 and abuts against the clamping portion 1211 of the first body 121, that is, the clamping portion 1211 of the first body 121 cooperates with the second body 122 to clamp the air pipe 22, so as to achieve the installation and fixation of the air pipe 22. Furthermore, by fixing the air pipe 22 on the shock absorbing member 12 , when the air pump is working, the vibration of the air pipe 22 can be absorbed by the shock absorbing member 12 and can be avoided from being directly transmitted to the bracket 11 , which helps to improve the shock absorbing effect.
[0056] In some embodiments, the thickness of the second body 122 at the receiving groove 1223 is less than the thickness of other parts of the second body 122. In this embodiment, because the receiving groove 1223 is located at the connection between the second body 122 and the first body 121, the thickness of the second body 122 at the receiving groove 1223 is thinner, and when the first body 121 transmits vibration to the second body 122, the vibration can be better absorbed by the second body 122, thereby improving the shock absorption effect.
[0057] In some embodiments, reference Figure 5 and Fig. 9The bracket 11 includes two supporting parts 111 arranged opposite to each other and a avoiding part 112 connected between the two supporting parts 111. The avoiding part 112 is formed into a groove structure. The first body 121 is accommodated in the avoiding part 112 and is clearance-matched with the avoiding part 112 to form a third gap 300. The width of the third gap 300 is 0.7mm-1.8mm. In this embodiment, the two supporting parts 111 are the basic structure of the bracket 11, which is used to form support when installed on the cleaning equipment. The negative pressure component 2 and the first body 121 sleeved on the negative pressure component 2 are installed on the avoiding part 112 of the bracket 11. The groove structure formed by the avoiding part 112 is used to avoid at least part of the first body 121. At the same time, the first body 121 is clearance-matched with the avoiding part 112, and a third gap 300 is formed between the two. Since the first body 121 of the shock absorbing member 12 is loosely matched with the avoidance portion 112 of the bracket 11, the first body 121 will collide with the avoidance portion 112 of the bracket 11 when transmitting vibration to the avoidance portion 112 of the bracket 11, thereby greatly weakening the vibration transmitted to the bracket 11. Optionally, the two support portions 111 and the avoidance portion 112 are integrally formed to improve the structural strength of the bracket 11.
[0058] Among them, the width range of the third gap 300 can be selected and set between 0.7mm and 1.8mm. For example, the width of the third gap 300 can be set to 0.7mm, 1.2mm or 1.8mm, etc. In actual application, the specific width of the third gap 300 can be set according to the vibration intensity of the negative pressure component 2. For example, the vibration intensity of the negative pressure component 2 is strong, and the third gap 300 is set to a larger width; the vibration intensity of the negative pressure component 2 is weak, and the third gap 300 is set to a smaller width. As an example, when the vibration intensity of the negative pressure component 2 is strong, the width of the third gap 300 can be set to 1.8mm; when the vibration intensity of the negative pressure component 2 is medium, the width of the third gap 300 can be set to 1.2mm; when the vibration intensity of the negative pressure component 2 is weak, the width of the third gap 300 can be set to 0.7mm.
[0059] In some embodiments, reference Figure 5 , Figure 6 and Fig. 9, the bracket 11 includes at least two supporting parts 111 and a avoiding part 112 connected between the at least two supporting parts 111, and the connecting hole 110 is opened in the supporting part 111. In this embodiment, at least two supporting parts 111 serve as the basic structure of the bracket 11, which is used to form a support when installed on the cleaning equipment. Among them, two or more supporting parts 111 can be provided. Optionally, two supporting parts 111 are provided, and the avoiding part 112 is located between the two supporting parts 111, and each side of the avoiding part 112 is connected to a corresponding supporting part 111. This is only exemplary and not restrictive. Among them, the connecting hole 110 is opened in the supporting part 111, and in the at least two supporting parts 111, the connecting hole 110 can be provided on a part of the supporting parts 111, or the connecting hole 110 can be provided on all the supporting parts 111, which is set according to the actual situation. The negative pressure assembly 2 and the first body 121 sleeved on the negative pressure assembly 2 are located in the avoidance portion 112 of the bracket 11 . The avoidance portion 112 constitutes a avoidance for at least part of the first body 121 .
