Description

Lock catch structure of handheld dust collector

Technical Field

The utility model relates to a dust collecting equipment, especially a hasp structure of hand-held type dust catcher.

Background

With the improvement of living standard, the requirements of people on the quality of life are higher and higher, and an important index for improving the quality of life is the guarantee of the living hygiene. The cleaning of dust is a delicate problem that needs to be solved daily in daily life, thereby opening up a huge market for vacuum cleaners. The handheld dust collector is not only popular with household cleaners due to its characteristics of small size, portability, no rope, large suction force and the like.

At present, a large number of handheld dust collectors only have a switch and a speed regulation function key, and some handheld dust collectors can continuously operate only by continuously pressing the switch key after the switch is turned on; after the switch of more handheld dust collectors is turned on, the whole machine can continuously and normally operate, and the whole machine stops working after the switch key is pressed again. No matter which kind of switch mode, the switch is mostly all set up on the operating personnel handheld handle, though such setting makes things convenient for the operating personnel to open and close the dust catcher, in the operation process, can be difficult to avoid carelessly touch the switch button, lead to the complete machine to stop the operation simultaneously. The long time, the frequent on-off caused by normal operation and error operation also has negative influence on the service life of the dust collector.

Disclosure of Invention

The utility model provides a lock catch structure of a handheld dust collector.

In order to achieve the above purpose, the utility model adopts the technical scheme that:

a lock catch structure of a handheld dust collector is provided with a switch, wherein the switch comprises a switch button, a switch button rotating shaft and a switch button connecting rod; the method is characterized in that:

a sliding button is arranged above a switch button of the dust collector and is provided with a sliding button pressing rod; the slide button pressure lever is positioned above the switch button connecting rod; the switch button connecting rod is erected on the switch button rotating shaft, and the front portion of the switch button connecting rod is uniformly upwarped and used for being matched with the slide button pressing rod.

The relevant content in the above technical solution is explained as follows:

1. in the above scheme, the slide button is arranged at a position above the switch button and close to the front, and the specific position arrangement is based on a comfortable distance touched by a thumb.

2. In the above solution, the stroke of the slide button (i.e. the displacement distance required for the technical effect of the slide button) is preferably the distance that the thumb of a normal person swings normally, and this distance is only used as a reference.

3. In the scheme, the front part refers to a section, close to the front, of the middle of a switch button connecting rod erected on the switch button rotating shaft, and the section is uniformly upwarped or uniformly lifted upwards; the terms of orientation such as front and back are used for better describing the technical scheme, wherein the specific meaning of front is that when the normal hand-held dust collector carries out dust collection operation, the direction in which an operator faces is front, and the direction in which the operator faces back is back.

The utility model discloses theory of operation and advantage as follows: the utility model adds a sliding button and makes special design for the traditional switch button connecting rod, so that the sliding button and the traditional switch button connecting rod are mutually matched to achieve the function of locking the switch; the utility model is applied to the household dust collector, and the user does not need to continuously press the switch when using the dust collector, thereby improving the use comfort level of the user; it is possible to avoid erroneous operation due to the index finger which may habitually press the switch.

FIG. 1 is a schematic diagram of a product suitable for use in the present invention;

FIG. 2 is a sectional view of the inner structure of the lock of the present invention;

fig. 3 is a schematic diagram of the switch and its components according to the present invention.

In the above drawings: 1. a switch; 2. a switch button; 3. a switch button rotating shaft; 4. a switch button connecting rod; 5. a slide button; 6. a slide button pressure lever.

Detailed Description

The invention will be further described with reference to the following drawings and examples:

example (b): referring to fig. 1 to 3, a locking structure of a handheld vacuum cleaner includes a switch 1, where the switch 1 includes a switch button 2, a switch button shaft 3, and a switch button connecting rod 4; the front end of the switch button connecting rod 4 is uniformly upwarped. A slide button 5 is arranged at the front position above the switch button 2 of the dust collector, and the slide button 5 is provided with a slide button press rod 6; the slide button pressure lever 6 is positioned above the switch button connecting rod 4; the stroke of the slide button 5 is designed according to the stroke of the thumb, so that the motion of the thumb can easily slide the slide button 5.

In the actual use process, the index finger presses the switch button 2, the switch button 2 rotates along the switch button rotating shaft 3, the rear end of the switch button connecting rod 4 presses the switch rocker, the switch rocker is pressed, and the whole machine is started, wherein the operation process of the whole switch 1 is common knowledge in the industry and is well known by common technicians. If the whole machine needs to operate continuously without continuously pressing the switch button 2, the thumb can be used for pushing the sliding button 5 forwards, the sliding button pressing rod 6 moves forwards to press the front end of the switch button connecting rod 4 to clamp the switch button connecting rod 4, and the whole machine can be in a power-on state continuously. In this state, the user does not need to continuously press the switch button 2, which is convenient for the user to use. When the whole machine needs to be closed, the sliding button 5 is forcibly moved backwards, the clamping position is withdrawn, the finger loosens the switch button 2, the switch button connecting rod 4 returns to the initial state, the switch is closed, and the whole machine stops working.

The arrangement can avoid the influence on the performance and the service life of the whole machine caused by frequent opening and closing of the whole machine due to the error operation of the index finger in the use process of a user.

The above embodiments are only for illustrating the technical concept and features of the present invention, and the purpose of the embodiments is to enable people skilled in the art to understand the contents of the present invention and to implement the present invention, which cannot limit the protection scope of the present invention. All equivalent changes and modifications made according to the spirit of the present invention should be covered by the protection scope of the present invention.
