A novel air outlet structure for floor scrubbers

Abstract

This utility model discloses a novel air outlet structure for a floor scrubber, relating to the field of floor scrubber technology. It includes a floor scrubber housing and a fan assembly with an air inlet and an air outlet. The floor scrubber housing further includes an inner chamber and an outer chamber. The fan assembly is detachably mounted in the inner chamber. Both the air inlet and outlet of the fan assembly face the outer chamber. A rubber gasket is also provided on one side of the fan assembly to ensure a tight seal between the air inlet port and the air inlet duct, and between the air outlet port and the air outlet duct. With both the air inlet and outlet of the fan assembly facing the outer chamber, when the fan assembly is running, the airflow at the air inlet port carries water into the machine and directly sprays it out of the outer chamber from the air outlet port, preventing water from remaining in the inner chamber. This avoids the situation where water is sucked in but cannot be completely discharged from the machine, thus preventing damage.

Description

Technical Field

[0001] This utility model relates to the field of floor scrubber technology, and in particular to a novel air outlet structure for a floor scrubber. Background Technology

[0002] A floor scrubber is a cleaning machine suitable for cleaning hard floors, simultaneously drying wastewater, and removing the wastewater from the site. It has advantages such as being environmentally friendly, energy-saving, and highly efficient.

[0003] In existing floor scrubber air duct designs, the air outlet is generally located inside the machine. However, since floor scrubbers come into contact with water, water is easily sucked into the machine during operation. If the air outlet is inside the machine, the water sucked in may not be completely expelled, potentially damaging the machine. Therefore, we propose a new type of floor scrubber air outlet structure to solve the above problems. Utility Model Content

[0004] This utility model provides a novel air outlet structure for floor scrubbers, which solves the technical problem that air outlets inside the current floor scrubbers can easily cause damage to the machine.

[0005] To solve the above-mentioned technical problems, this utility model provides a novel air outlet structure for a floor scrubber, including a floor scrubber housing and a fan assembly with an air inlet and an air outlet. The floor scrubber housing further includes an inner chamber and an outer chamber. The fan assembly is detachably installed in the inner chamber. The air inlet and the air outlet of the fan assembly both face the outer chamber. A rubber pad is also provided on one side of the fan assembly.

[0006] Preferably, an air inlet port and an air outlet port are provided on the side of the inner chamber near the outer chamber, and a first port and a second port are provided on the rubber pad. The air inlet port is flush with the second port and the air inlet duct, and the air outlet port is flush with the first port and the air outlet duct.

[0007] Preferably, a second snap-fit ​​assembly, a first snap-fit ​​assembly, and fasteners are respectively provided between the fan assembly and the floor scrubber housing.

[0008] Preferably, the second snap-fit ​​assembly includes a second snap-fit ​​protrusion disposed at the bottom of the fan assembly and a snap-fit ​​groove opened in the inner chamber of the floor scrubber housing.

[0009] Preferably, the first snap-fit ​​assembly includes a buckle provided on the fan assembly and a first snap-fit ​​protrusion provided on the outer wall of the floor scrubber housing.

[0010] Preferably, the fastener includes a bolt that threadedly connects the floor scrubber housing to the fan assembly.

[0011] Preferably, the first port is further provided with a shoulder, which is at least partially embedded in the air outlet port.

[0012] Preferably, a positioning component is also provided between the rubber pad and the fan assembly.

[0013] Preferably, the positioning component includes a positioning protrusion provided on one side of the rubber pad and a positioning groove opened on one side of the fan component.

[0014] Preferably, the outer chamber is provided with a concave arc-shaped surface.

[0015] Compared with related technologies, this utility model has the following beneficial effects: 1. Compared with traditional floor scrubbers, this utility model features a machine casing with an inner chamber and an outer chamber, as well as a rubber gasket. The rubber gasket ensures the sealing between the air inlet port and the air inlet duct, and between the air outlet port and the air outlet duct. The air inlet and air outlet ducts of the fan assembly face the outer chamber. When the fan assembly is running, the airflow at the air inlet port carries water into the machine and sprays it directly out of the outer chamber from the air outlet port, without leaving any water in the inner chamber. This avoids the situation where water is sucked in but cannot be completely discharged from the machine, thus preventing damage to the machine. Attached Figure Description

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0019] Example 1 like Figures 1-8 As shown, a novel floor scrubber air outlet structure includes a floor scrubber housing 2 and a fan assembly 6 having an air inlet duct 62 and an air outlet duct 61. The floor scrubber housing 2 also includes an inner chamber 22 and an outer chamber 21. The fan assembly 6 is detachably installed in the inner chamber 22. The air inlet duct 62 and the air outlet duct 61 of the fan assembly 6 both face the outer chamber 21. A rubber pad 7 is also provided on one side of the fan assembly 6. The floor scrubber housing 2 also includes an inner chamber 22 and an outer chamber 21. The fan assembly 6 is detachably installed in the inner chamber 22. The air inlet duct 62 and the air outlet duct 61 of the fan assembly 6 both face the outer chamber 21. A rubber pad 7 is also provided on one side of the fan assembly 6. The rubber pad 7 ensures the sealing between the air inlet port 24 and the air inlet duct 62, and between the air outlet port 23 and the air outlet duct 61. When the fan assembly 6 is running, the airflow at the air inlet port 24 carries water into the machine and sprays it directly out of the outer chamber 21 of the machine from the air outlet port 23. It will not remain in the inner chamber 22 of the machine, thus avoiding the situation where water is sucked in and cannot be completely discharged from the machine, which could damage the machine.

[0020] Example 2 like Figures 5-7As shown, an air inlet port 24 and an air outlet port 23 are provided on the side of the inner chamber 22 near the outer chamber 21. A first port 71 and a second port 72 are provided on the rubber gasket 7. The air inlet port 24 is flush with the second port 72 and the air inlet channel 62. That is to say, the size of the second port 72 is adapted to the air inlet port 24 and the air inlet channel 62, so that the rubber gasket 7 can ensure the sealing between the air inlet port 24 and the air inlet channel 62, and prevent water from leaking into the machine when it is sucked in. The air outlet port 23 is flush with the first port 71 and the air outlet channel 61. That is to say, the size of the first port 71 is adapted to the air outlet port 23 and the air outlet channel 61, which can ensure maximum drainage. The rubber gasket 7 can ensure the sealing between the air outlet port 23 and the air outlet channel 61, and ensure that water does not leak into the machine when it is discharged. like Figures 3-6 As shown, a second snap-fit ​​component 4, a first snap-fit ​​component 3, and a fastener 1 are respectively provided between the fan assembly 6 and the floor scrubber housing 2, making the installation between the fan assembly 6 and the floor scrubber housing 2 more compact, secure, and precise, while also facilitating later disassembly and maintenance. like Figure 6 As shown, the second snap-fit ​​assembly 4 includes a second snap-fit ​​protrusion 42 provided at the bottom of the fan assembly 6 and a snap-fit ​​groove 41 opened in the inner chamber 22 of the floor scrubber housing 2, which makes the installation between the air intake assembly and the floor scrubber housing 2 more precise and prevents the fan assembly 6 from being displaced horizontally during the initial installation between the fan assembly 6 and the floor scrubber housing 2. like Figure 6 As shown, the first snap-fit ​​component 3 includes a snap-fit ​​32 provided on the fan assembly 6 and a first snap-fit ​​protrusion 31 provided on the outer wall of the floor scrubber housing 2, which further restricts the relative horizontal displacement between the air intake assembly and the floor scrubber housing 2 during installation. like Figure 3 , Figure 4 As shown, the fastener 1 includes bolts. The fastener 1 connects the floor scrubber housing 2 to the fan assembly 6 by thread. The fastener 1 is used to tighten the connection and prevent longitudinal and horizontal displacement between the air intake assembly and the floor scrubber housing 2 during installation. like Figure 2 , Figure 7 As shown, a shoulder 73 is also provided on the first port 71. The shoulder 73 is at least partially embedded in the air outlet port 23. When the fastener 1 connects the floor scrubber housing 2 and the fan assembly 6 by thread, the fan assembly 6 squeezes the rubber pad 7, so that the shoulder 73 on the rubber pad 7 is embedded in the air outlet port 23, thereby achieving an interference fit connection between the rubber pad 7 and the air outlet port 23 and further improving the sealing performance. like Figure 7 As shown, a positioning component 8 is also provided between the rubber pad 7 and the fan assembly 6, which facilitates the precise and quick installation of the rubber pad 7 on the fan assembly 6; like Figure 7 As shown, the positioning component 8 includes a positioning protrusion 81 provided on one side of the rubber pad 7 and a positioning groove 82 opened on one side of the fan assembly 6. The positioning protrusion 81 is inserted into the positioning groove 82 to complete the positioning of the rubber pad 7 and the fan assembly 6 during installation. like Figure 5 As shown, the outer chamber 21 is provided with a concave arc-shaped surface 210. The concave arc-shaped surface 210 can guide the airflow when water-laden air is drawn in. Secondly, when water is discharged from the machine, the arc-shaped surface 210 of the outer chamber 21 can provide protection and prevent water from spraying everywhere.

[0021] Working principle: such as Figures 1-8 As shown, the blower assembly 6 has a rubber-coated gasket 7, which is made of soft rubber. During assembly, the blower assembly 6 and the floor scrubber housing 2 are fixed together by two snap-fit ​​components: the first snap-fit ​​component 3 and the second snap-fit ​​component 4. Two screws are tightened into the fastener 1 to make the blower assembly 6 and the floor scrubber housing 2 fit tightly together. Because the rubber-coated gasket 7 is provided at the contact point, and the material is soft, it is subjected to the force of the two snap-fit ​​components (first snap-fit ​​component 3, second snap-fit ​​component 4) and the two screws (fastener 1) to press against the floor scrubber housing 2. The airflow is sealed by an interference fit. The airflow enters the machine through the air inlet port 24, flows through the fan assembly 6, and then flows out of the machine through the air outlet port 23. At the air outlet port 23, the rubber pad 7 has a shoulder 73 embedded in the air outlet port 23. Under the action of the first snap-fit ​​assembly 3, the second snap-fit ​​assembly 4, and the fastener 1, the two parts are interference-fitted. When the airflow from the air inlet port 24 carries water into the machine, it is sprayed directly out of the machine from the air outlet port 23 and will not remain inside the machine.

[0022] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
