[0041] Next, refer to Figures 1 to 6 Describe the nozzle assembly and the gas stove according to some embodiments of the present application.

[0042] The present application provides a nozzle assembly, as Figures 1 to 4 shown. The nozzle assembly includes a nozzle 3, a first filter element 1, and a second filter element 2.

[0043] The nozzle 3 is used to be installed on the burner head assembly of the gas stove, specifically at the inlet of the ejector tube of the burner head assembly, so as to allow gas and primary air to enter the ejector tube; a plurality of air guiding holes are provided on the side wall of the nozzle 3, and the plurality of air guiding holes are arranged at intervals around the circumference of the nozzle 3, and air in the external environment can enter the nozzle 3 through the plurality of air guiding holes to supplement the primary air participating in combustion.

[0044] The first filter element 1 is circumferentially sleeved on the outside of the nozzle 3 in a fitting manner, and a plurality of first grooves 11 are recessed on the side of the first filter element 1 facing away from the nozzle 3, and the plurality of first grooves 11 respectively cover the plurality of air guiding holes; the second filter element 2 is circumferentially sleeved on the outside of the first filter element 1 in a fitting manner, and a plurality of second grooves 21 are recessed on the side of the second filter element 2 facing away from the nozzle 3, and the plurality of second grooves 21 respectively sleeve on the outside of the plurality of first grooves 11.

[0045] A first through hole 12 is formed on the circumferential side wall of each first groove 11, and a second through hole 22 is formed on the circumferential side wall of each second groove 21. For any relatively set of first groove 11 and second groove 21, the circumferential side wall of the first groove 11 is in contact with the axial side wall of the second groove 21, and the first through hole 12 and the second through hole 22 partially overlap. Thus, a filter hole for filtering the air guiding holes is formed through the overlapping part of the first through hole 12 and the second through hole 22, and the problem of the filter hole having too large a size caused by using only the first through hole 12 or the second through hole 22 as the filter hole can be avoided, thereby effectively playing a filtering role, preventing insects from entering the nozzle 3 through the air guiding holes and nesting and forming a net inside the nozzle 3 to cause blockage of the nozzle 3, and ensuring the normal use of the gas stove.

[0046] Meanwhile, since the first through-hole 12 and the second through-hole 22 are openings formed on the circumferential side walls of the corresponding groove portions, the height of the openings can be elongated. The height of the openings is the dimension of the openings along the axial direction of the corresponding groove portions. Thus, it can effectively prevent bugs from entering the air guiding holes and effectively ensure sufficient ventilation volume.

[0047] In an embodiment of the present application, preferably, for any one of the first groove portions 11, the number of the first through-holes 12 is multiple, and the multiple first through-holes 12 are arranged at intervals around the circumference of the first groove portion 11 where they are located; for any one of the second groove portions 21, the number of the second through-holes 22 is multiple, and the multiple second through-holes 22 are arranged at intervals around the circumference of the second groove portion 21 where they are located.

[0048] For a pair of opposite first groove portions 11 and second groove portions 21, the multiple first through-holes 12 and the multiple second through-holes 22 are correspondingly opposite and arranged in a staggered manner, so as to form multiple filter holes around the air guiding holes, so as to effectively prevent bugs from entering the nozzle 3 through the air guiding holes while ensuring sufficient air volume can pass through the air guiding holes into the nozzle 3.

For example, if the area of the nozzle 3 where the air guiding holes are formed is a polygon, and the first filter member 1 is also in the same polygon shape, then the second filter member 2 is also bent into the same polygon to fit and sleeve.

[0050] In this embodiment, preferably, one end in the length direction of the second filter member 2 is provided with a cable tie, and the other end in the length direction of the second filter member 2 is provided with a cable tie buckle. When the second filter member 2 is bent and sleeved on the outside of the first filter member 1, the cable tie can be inserted into the cable tie buckle and clamped in the cable tie buckle, so as to tie the second filter member 2 to the outside of the nozzle 3 and the first filter member 1, and by adjusting the length of the cable tie inserted into the cable tie buckle, the tightness of the tying can be adjusted.

[0051] Meanwhile, due to the socketing cooperation between the first groove portion 11 of the first filter member 1 and the second groove portion 21 of the second filter member 2, when the second filter member 2 is tied and fixed, the fixing and installation of the first filter member 1 outside the nozzle 3 are also completed.

[0052] In this embodiment, preferably, the first filter member 1 is a complete ring matching the nozzle 3, so that it can be sleeved on the nozzle 3 and then fixed by the second filter member 2.
