Description

M241132 V. Creation Instructions (l) '[Technical Field of New Type] This creation relates to a water spray grab with a micro-pressure control device, especially a water spray grab with a micro-pressure control device. The micro-pressure switch uses a very short stroke to match the change in hydraulic pressure to control the on / off of a water flow control unit, which has the advantages of easy operation and extremely short pressing stroke. [Previous technology] As shown in the eighth figure, the conventional water jet grab system includes: 'a water spray gun body 80, which is provided with a grip 8 1 which forms a water passage 81 1 inside, The water passage 811 allows water to be sprayed out of the water spraying body 809, and a water outlet button 82 is pivotally connected to the handle 81 of the water spraying body 80. The water outlet 82 is provided with a valve body 821, and the valve body The 821 series extends into the water channel 811 'to control the passage of the water channel 811 to open / close the water source. When the conventional water spray body 80 is used to provide water spray, it is necessary to press the water outlet button 82 with a finger (usually an index finger) with a large force to keep the valve body 821 away from the water passage 8 11. Only the water can be ejected from the water spray body 80, but this requires a large amount of force, and the design that firmly presses the water outlet button 82 can cause considerable inconvenience to the user, and even cause discomfort to the fingers.

Secondly, it is known that the moving distance of the valve body 821 must be at least equal to or greater than the diameter d of the water passage 81, assuming that the diameter d is 10 mm, the row of pressing the switch & S is at least 10 mm, but if the Save effort and use the principle of leverage (assuming that the facility arm is twice the resistance arm), the stroke S required for pressing and moving will be as high as 20 mm. And in principle, the larger the flow, the more effortless the water spray grab, the more pressure it needs

V. Creation instructions (2) The journey has become larger, so there is pressing. Therefore, it is necessary to develop new disadvantages. * ° 缺点 is too long. Structure to overcome the above traditional structure. [New content] A spray with a micro-pressure water control device The main purpose of this creation is to provide water grabbing, which is a relaxing micro-pressure water control. The second purpose of this creation is water grabbing, which has a short press stroke. In order to solve the lack of practice, the following: 'The technical scheme used to provide a spray with a micro-pressure water control device is to provide this creation as a water spray grab with a micro-pressure water control device, which includes a water inlet channel, a water outlet channel and a A water flow control unit located between the water inlet channel and the water outlet channel, the water flow control system includes: a main water channel 'having a diverter opening, a first container chamber and a confluent opening in this order; a diverter channel whose flow rate Smaller than the main water channel, the diverting water channel has an introduction channel, a second container, and an outlet channel in sequence; a displaceable and water-resistant partition film is used to separate the first container and the second container An elastic force generating element is provided at one end of the separation membrane to generate a predetermined small thrust. When the pressure of the first chamber is greater than the sum of the pressure of the second chamber and the small thrust, the separation membrane will move. Open so that the main and road are in a path shape, and 'when the pressure of the first chamber is not greater than the sum of the pressure of the second 4 chamber and the small thrust, the separation membrane will block the first ~ Room makes the main channel Disconnected; M241132

V. Creation description (3) It is located on the outlet of the diverting water channel. When the micro is' when the micro-pressure valve is not pressed by the micro-pressure valve, the system is blocked when the outlet is pressed. Make the lead-out path of the monument in a conductive state> The above-mentioned purpose and advantages of this creation can be easily understood from the detailed description and accompanying drawings of the selected embodiment below. The following examples and drawings are used to explain this creation in detail: [Embodiment] 'This creation is a water spray with a micro-pressure water control device. Please refer to the first to sixth figures, which includes a water inlet channel 11. A water outlet channel 12 and a water flow control section 3 between the water inlet channel 11 and the water outlet channel 2

The flow control unit 13 includes: Θ & a main water channel 20, which has a diverting opening 21, a first container 22, and a confluent opening 2 3 in order; a diverting water channel 30, whose flow is less than the main Water channel 20, the diverting water channel 30 has an introduction channel 31, a second container 32 and an outlet channel 33 in sequence;

A displaceable and water-resistant separation film 40 is used to separate the first and second storage chambers 22 and 32. An elastic force generating element 41 is provided at one end of the separation film 40 corresponding to the second storage chamber 32. In order to generate a predetermined small thrust, when the pressure of the first storage chamber 22 is greater than the pressure of the second storage chamber 32 and the small thrust _, the separation membrane 40 will be removed and the main water channel 20 will be rendered Path-like ^ Also, when the pressure of the first container 22 is not greater than the sum of the pressure of the second container 32 and the small thrust, the separation film 40 will block the first container 22 and make the main The water channel 20 is in the shape of an open circuit; a micro-pressure valve member 50 is located on the exit 33 of the branch water channel 30,

Page 7 M241132 V. Creation instructions (4) When the micro-pressure valve member 50 is pressed, the lead-out path 33 is blocked, and when the micro-pressure valve member 50 is not pressed, it is the lead-out path 33 In a conducting state Γ / More specifically, 'the first container 22 of this creation is provided with a partition 221 substantially perpendicular to the partition film, and the partition film 40 contacts or separates the partition 2 2 1 to control the The first chamber 22 is flowable or blocked. Please refer to the 7th figure of the younger brother. Because the separation film 40 is a soft and deformable film, a hard, tapered auxiliary element 42 can be added between the separation film 40 and the elastic force generating element 41, so that The separation film 40 maintains its proper shape, and the small thrust of the elastic force generating element 41 can be evenly distributed on the separation film 40. Secondly, the micro-pressure valve member 50 further includes a pressing button 51 and a spring water plug 52 (refer to FIG. 7 for cooperation), and when the user presses the button 51 to touch the spring water base 5 2 ', even if the spring water plug 5 2 can be maintained at the position after being touched; when the user presses the pressing button 51 again, the elastic water plug 52 is held still after being changed by being touched ^. The action principle of this creation is detailed here: First, 'connect the water spray to the water source (not shown in the figure)' After turning on the water source, the flushed water flows into the water channel and the water will pass through the water channel. The main water channel 20 and the diverted water channel 30 flow into the first and second chambers 22 and 32, respectively, and generate a high instantaneous high pressure. ~ ~ At this time, if the micro-pressure valve member 503 is in a blocking state, both the second container chamber 22 and the second container chamber 32 are transmitted at this time because the elastic force generating element 41 is under pressure. State, that is, the exit chamber 32 is also open-circuited, so the first inlet pressure is the same as the high pressure at the same time, but a small thrust is generated, and the first chamber M241132 V. Creation Note (5) 22 The pressure is not greater than this The sum of the pressure of the second chamber 32 and the small thrust. Therefore, 'the separation membrane 40 still presses the partition plate 221 of the first container 22, so that the entire main water channel 20 is also a road shape, that is, there is no water flowing out of the water outlet channel 2; another case is if the The micro-pressure valve 5 is not in a state of being pressed, that is, the lead-out path 33 is in a conductive state. At this time, when water is introduced into the first valley chamber 22 and the first container chamber 32 instantly, the second The pressure of the chamber 32 will decrease due to the outflow of water from the exit channel 33. Although the elastic force generating element ο generates a small thrust, the pressure of the first chamber 22 is greater than the pressure of the second chamber 32 The sum of this small thrust. Therefore, the partitioning film 40 will be removed by hydraulic pressure from the partition plate 221, so that the entire main water channel 20 is in the shape of a passage, and the water liquid flows through the outlet channel 12 and flows out. Of course, if the user gently presses the micro-pressure valve 50 again, even if the lead-out path 33 is in a barrier shape, the pressure of the first valley chamber 22 is not greater than the first valley chamber 22 because the elastic force generating element 41 generates a thrust force. The sum of the pressure of the second chamber μ and the small thrust. Therefore, the separation film 40 will be pushed by the hydraulic pressure, and the partition plate 221 of the first container 22 will be pressed, so that the entire main water channel 20 will be cut off, and the water on the water outlet channel 12 will be further closed. To sum up, the advantages and effects of ‘this creation can be summarized as follows: [1] The town easily presses and controls the water. In the conventional water blocking action, if the water flow is closed while flowing, it must overcome the resistance of the impact of the water flow.% T ^ # ^ Γ / J 7L It takes more force to close when closing. However, the lead-out and f-aperture of this creation are small. It is assumed that the diameter is 2mm, and the flow rate is small. Therefore, when it is closed, the resistance caused by the water flow is easy to press and control the water. , ...,

M241132 V. Creation Instructions (6) [2] The stroke of pressing is short. The water flow in this creation is controlled by the conduction or blocking of the outlet channel of the flow channel, and the flow rate is small, and the aperture is 4, and assuming that the aperture is 2mm, a displacement (stroke) of i 2 mm can be achieved. In contrast, the design of the direct shut-off water source on the j track (assume 10mm) is theoretically a travel distance of 10 °, so the travel is extremely short. As mentioned above, the spirit and scope of any of the first embodiment of the present embodiment is only early. Where did the early modification and change > (really reach the molding application. The purpose of explanation is to make the relationship that is well-known and has been in line with the special technology and profit law.
