[0002] Industrial vacuum cleaners are a kind of environmentally friendly cleaning equipment commonly used in industry. Its main function is to collect waste, filter and purify air, and clean dust and particles in the environment during industrial production. The main components of industrial vacuum cleaners include vacuum pumps, hoses and nozzles of various shapes. Its working principle is that through the high-speed operation of the electric exhaust fan, an instantaneous vacuum is formed inside the vacuum cleaner, making the internal air pressure much lower than the external air pressure. Under the action of this air pressure difference, dust and dirt are sucked into the vacuum cleaner barrel. After being filtered by the high-efficiency filter, the dust is left in the dust collection barrel, and the purified air is re-discharged into the room through the motor, which not only plays the role of cooling the motor, but also achieves the purpose of purifying the air. Industrial vacuum cleaners are widely used in many fields such as textiles, chemicals, machinery, cement, steel, semiconductors, and pharmaceutical manufacturing. In these fields, it can effectively prevent the hazards of some occupational diseases and improve production efficiency.

[0003] In industrial production environments, vacuum cleaners are commonly used cleaning tools. However, existing industrial vacuum cleaner nozzles are usually fixed in width and cannot be adjusted according to actual needs, resulting in the need to replace different nozzles in different cleaning scenarios. This method requires manual replacement of the nozzle, which is not convenient to use and affects the vacuum cleaning efficiency. In order to solve this problem, the utility model proposes an industrial vacuum cleaner nozzle structure with adjustable nozzle width. Utility Model Content

[0011] Furthermore, an anti-slip handle is sleeved on the annular surface of the dust suction connecting rod.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] 1. The utility model improves the suction nozzle structure of the existing vacuum cleaner and realizes the adjustability of the suction nozzle width to meet the cleaning needs of different cleaning scenes. Through the adjustment mechanism, the user can adjust the suction nozzle width according to different cleaning scenes to adapt to different cleaning needs and environments, so that the suction nozzle can play the best dust collection effect in various scenes, without the need to frequently replace the suction nozzle, which increases the flexibility and convenience of use.

DETAILED DESCRIPTION

[0026] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Example:

[0028] like Figures 1 to 7 As shown, an adjustable suction nozzle structure of an industrial vacuum cleaner includes a first dust suction bin 4, a second dust suction bin 6 is arranged on the front side of the first dust suction bin 4, a telescopic soft connecting piece 5 made of silicone material is arranged at the connection between the first dust suction bin 4 and the second dust suction bin 6, a dust suction tube 3 is connected to the upper left side of the annular surface of the first dust suction bin 4, a plug connector 2 is fixedly provided at the upper end of the dust suction tube 3, a dust suction connecting rod 1 is detachably plugged into the plug connector 2, and the dust suction connecting rod 1 is used to be connected to the hose of an external industrial vacuum cleaner, and an adjustment mechanism 7 is arranged between the first dust suction bin 4 and the second dust suction bin 6. This design solves the problem that the suction nozzle of the existing industrial vacuum cleaner is usually a fixed width structure and cannot be adjusted according to actual needs, resulting in the need to replace different suction nozzles in different cleaning scenarios. This method requires manual replacement of the suction nozzle, which is not convenient to use and affects the dust suction cleaning efficiency.

[0029] The adjustment mechanism 7 includes a driving assembly 71 and a rack plate 72. The driving assembly 71 is arranged on the upper side of the annular surface of the first dust suction bin 4. The rack plate 72 is suspended on the upper side of the first dust suction bin 4, and its right end is fixedly connected to the second dust suction bin 6. The adjustment mechanism 7 is arranged to facilitate the adjustment of the distance between the first dust suction bin 4 and the second dust suction bin 6, thereby realizing the adjustment of the width of the suction nozzle. Through the adjustment mechanism 7, the user can adjust the width of the suction nozzle according to different cleaning scenes to adapt to different cleaning needs and environments, so that the suction nozzle can play the best dust suction effect in various scenes, without the need to frequently replace the suction nozzle, which increases the flexibility and convenience of use. The driving assembly 71 can drive the rack plate 72 to move left and right, thereby driving the second dust suction bin 6 to move, so that the distance between the first dust suction bin 4 and the second dust suction bin 6 changes, and the dust suction width is adjusted.

[0030] The driving assembly 71 is composed of a fixed rod 711, a sleeve handle 712, a gear 713, a reset spring 714 and an engagement tooth pattern 715. The fixed rod 711 is fixedly arranged on the annular surface of the first dust collecting bin 4. The fixed rod 711 is sleeved with a reset spring 714. The fixed rod 711 on the upper side of the reset spring 714 is sleeved with a gear 713. The annular surface of the fixed rod 711 and the inner annular surface of the gear 713 are engraved with an engagement tooth pattern 715. The gear 713 is meshed with the fixed rod 711 through the engagement tooth pattern 715. The upper side of the gear 713 is fixedly provided with a sleeve handle 712. The gear 713 is meshed with the rack plate 72, and its thickness is greater than that of the rack plate 72. The drive assembly 71 is provided to facilitate driving the rack plate 72 to move, thereby realizing the adjustment of the second dust collecting bin 6. When the user needs to adjust the width of the suction nozzle, the sleeve handle 712 is pressed downward to separate the meshing teeth 715 thereon from the meshing teeth 715 on the fixed rod 711, and the gear 713 is unlocked and is in a rotatable state. The sleeve handle 712 is rotated to drive the gear 713 to rotate. Since the gear 713 is meshed with the rack plate 72, the rotation of the gear 713 will drive the rack plate 72 to move horizontally, and the rack plate 72 will drive the second dust suction bin 6 to move, thereby changing the width of the suction nozzle. When the user releases the sleeve handle 712, the reset spring 714 will automatically return the gear 713 to the initial position, and at the same time, the gear 713 will be locked by the meshing teeth 715, so that the gear 713 is fixed in the current position, thereby ensuring the stability of the rack plate 72 and the second dust suction bin 6.

[0031] The first dust collection bin 4 is provided with a limit slide groove 42 on both sides of the inner wall, and the second dust collection bin 6 is provided with a support bar 61 on both sides of the inner wall, and the left end of the support bar 61 extends into the first dust collection bin 4 and is inserted into the limit slide groove 42. The set limit slide groove 42 and support bar 61 play the role of limit support for the second dust collection bin 6, and provide a clear track for the movement of the second dust collection bin 6, which not only limits the movement range of the second dust collection bin 6, but also ensures smooth and linear movement during the adjustment process. When the user adjusts the width of the suction nozzle through the drive assembly 71, the second dust collection bin 6 will move smoothly horizontally under the guidance of the support bar 61 and the limit slide groove 42. The limit slide groove 42 limits the up and down movement of the support bar 61 and the second dust collection bin 6, thereby ensuring stability and accuracy during the adjustment process.

[0032] A connector 41 is fixedly provided on the annular surface of the first dust collection bin 4. The connector 41 serves as the connection point between the dust collection tube 3 and the dust collection bin, ensuring the stable connection of the dust collection tube 3. The lower end of the dust collection tube 3 extends into the connector 41 to form a tight connection. The design ensures airtightness during the dust collection process and prevents the loss of suction force. A limit baffle 22 is fixedly provided on the annular surface of the dust collection tube 3 near the lower end, and the diameter of the limit baffle 22 is larger than the diameter of the dust collection tube 3 but smaller than the inside of the connector 41. The limit baffle 22 is located inside the connector 41, ensuring that the dust collection tube 3 will not fall off from the connector 41. A support spring 21 is sleeved on the dust collection tube 3 between the connector 41 and the plug 2. The support spring 21 provides elastic support for the dust collection tube 3, while allowing the lower end of the dust collection tube 3 to telescopically move inside the first dust collection bin 4 and return to its original position.

[0033] The vacuum cleaner connecting rod 1 is covered with an anti-skid grip 11, which is made of rubber material. The main function of the anti-skid grip 11 is to increase the friction when holding, to prevent the user from slipping off the connecting rod due to sweaty hands or humid environment, thereby improving the safety and stability of operation. The soft anti-skid grip 11 can provide a better grip feeling and reduce the discomfort of the hand when using the vacuum cleaner for a long time.

[0034] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made on the basis of the above description. It is impossible to list all the implementation methods here. All obvious changes or modifications derived from the technical solution of the present invention are still within the protection scope of the present invention.
