The traditional aerosol product is mostly to spray out the content by pressing valve rod, and the pressing stroke of this kind of pressing structure is usually large, and it is relatively laborious, and the spraying amount of single pressing is also large, which needs to be improved.

[0003] In addition, the structure design of general aerosol product is mostly only suitable for normal spraying (the nozzle is upward and the bottle body is normal), and cannot normally spray after the bottle is inverted. In order to solve the problem of normal spraying after inversion, Chinese patent 200820173840.8 discloses a double-tube aerosol bottle, which comprises a bottle body, a long spray pipe and a short spray pipe, and is adapted to normal and inverted spraying through two spray pipes. But this structure not only has large double-pipe structure size, but also needs to consider increasing the bottle opening or reducing the diameter of each spray pipe for standard specification bottle body; and when the liquid is full, the liquid will be sprayed from the two spray pipes at the same time in normal use, causing waste. SUMMARY

[0018] The application will be further described in conjunction with the accompanying drawings: Figures 1 to 5 The application will be further described in conjunction with the accompanying drawings:

[0019] The application will be further described in conjunction with the accompanying drawings: Figure 1 And 2 The single universal aerosol valve comprises a cup 1, a valve body 2 and a valve stem 3, the lower end of the valve body 2 is provided with a feed inlet 201 which is communicated to the valve cavity 20 of the valve body 2, the feed inlet 201 is connected to the liquid guide pipe 7, the valve stem 3 is inserted into the valve cavity 20 through the opening 202 at the upper end of the valve body 2, the valve stem 3 is provided with a spray channel 31 and a valve hole 32 which is communicated with the spray channel 31, the valve hole 32 is located at the side of the valve stem 3, the opening 202 at the upper end of the valve body 2 and the cup 1 are provided with a sealing ring 4, the sealing ring 4 covers the valve hole 32 of the valve stem 3 and is configured to communicate the valve hole 32 with the valve cavity 20 when the valve stem 3 is pressed down or tilted, the valve body 2 is provided with a reset member 5 for resetting the valve stem 3.

[0020] Specifically, referring to the accompanying drawings, Figure 3 The valve cavity 20 is provided with a valve core mechanism 6, the valve core mechanism 6 comprises a valve core seat 61, a valve bead 62 and a valve bead seat 63, the valve core seat 61 has an upwardly open abutting groove 610, the lower end of the valve stem 3 is opposite to the abutting groove 610 and is provided with a positioning ring table 33 on the outer wall of the valve stem 3, the reset member 5 comprises a reset spring, one end of the reset spring is sleeved into the lower end of the valve stem 3 and abuts to the positioning ring table 33, the other end of the reset spring is arranged in the abutting groove 610. In order to ensure that the reset spring is firmly connected with the valve stem 3 when it is deformed, the lower end of the valve stem 3 is in an outwardly convex shape so as to form a ring-shaped recess 34 between the convex part and the positioning ring table 33, the upper end of the reset spring is nested in the ring-shaped recess 34.

[0021] The application will be further described in conjunction with the accompanying drawings: Figure 4The inner wall of the valve rod 3 at the position of the valve hole 32 is inwardly recessed to form an inner recess 35, and the inner ring of the sealing ring 4 is tightly attached to the inner recess 35. This structure not only makes the inner ring of the sealing ring 4 better attached to the valve hole 32 to ensure the sealing performance, but also can quickly expose the valve hole 32 when the valve rod 3 is pressed downward or pushed sideways. The lower end of the valve rod 3 is outwardly convex, so that the rod body below the inner recess 35 of the valve rod 3 forms a limiting portion 36 abutting against the sealing ring 4. Under the action of the limiting portion 36, the valve body 3 is prevented from being completely inserted into the sealing cup 1, and the contact between the limiting portion 36 and the sealing ring 4 is more closely under the action of the elastic force, thereby ensuring the sealing performance.

[0022] When the valve rod 3 is pushed sideways, the inner recess 35 is pressed towards the valve cavity 20, and finally the valve hole 32 is exposed. Compared with the general pressing structure, the reset stroke is shorter, which is labor-saving and easy to push. According to the amount of tilting of the valve rod 3, the amount of spraying of the contents can also be simply controlled. When pressing, the valve hole 32 is located at a lower position (at the sealing position of the sealing ring 4), so it also has a shorter reset stroke. It does not need to be pressed deeply as the traditional valve rod (the valve hole is located above the sealing ring, and a certain distance needs to be pressed downward to pass through the sealing ring and reach the valve cavity). Therefore, the product is particularly suitable for use in the field of cosmetics and foam, which has high requirements for the precision of spraying.

[0023] The valve seat 63 is located above the inlet 201 of the valve body 2, the bottom end is provided with a first channel 631 connected to the inlet 201, and the side wall is provided with a gas hole 632 connected to the outside of the valve body 2. The valve bead 62 is movably arranged in the valve seat 63 and can close the first channel 631 when the valve body 2 is placed in the normal direction, and expose the first channel 631 when the valve body 2 is inverted. The valve seat 63 is fixed with the inner cavity wall of the valve body 2, and the bottom of the valve seat 63 is provided with a plurality of second channels 633 for connecting the inlet 201 and the valve cavity 20. The valve seat 63 is arranged below the valve core seat 61, and the bottom of the valve core seat 61 is provided with an embedded portion 611 embedded in the top opening of the valve seat 63. After the valve bead 62 is placed in the valve seat 63, the valve core seat 61 and the valve seat 63 are assembled to limit the valve bead 62 in the valve seat 63. Referring to the drawings Figure 5 When the valve body 2 is inverted, the valve bead 62 is moved away from the first channel 631 under the action of gravity to expose the channel opening. At this time, the propellant enters the valve seat 63 through the gas hole 632, and then enters the valve cavity through the first channel 631 and the second channel 633, thereby completing the direction of the contents spraying, thereby ensuring that the product can still be normally sprayed in the inverted state.

[0024] The above preferred embodiments should be regarded as an example of the implementation of the application. Any technical deduction, replacement, improvement, etc. similar to or based on the application should be regarded as the protection scope of the patent.
